Thanks, Oliver. I did visit a house with a heat pump under the Nesta scheme. I found it a very valuable experience. I was struck by how comfortable the house was temperature wise. A very comfortable all enveloping heat and surprised by the size of the heat pump. I am also getting £100 off my final Octopus installation bill. I think your video will prove very useful to people who cannot do an in person visit.

Octopus quoted me for an install on 8mm plastic microbore, which they said was Ok as long as the pipe had the word "Barrier" on it. In the end didn't go ahead as their "one size fits all" approach would have meant ripping our new build house apart! Also they were insisting that MCS regs meant new hot water tank had to be replaced... Very frustrating... Off to see if my local Heat Geek can come up with a better solution!

Yeah, Octopus are targeting the easy-install majority and doing is exactly by-the-book. If you need more custom designed solutions then Heat Geeks are definitely the way forward.

A very interesting and well presented video. I would like to change from my existing oil fired central heating system to a heat pump but at present it is difficult to see how it will save me enough for me to break even within a meaningful time period. The current price of oil is about 65p/litre. Allowing for boiler efficiency (about 90% on my condensing boiler) and that there are about 10kwh in each litre of oil, I reckon I am getting energy at about 7.5p/kwh. Typical electricity tariffs are around 30p/kwh peak and 8p/kwh off-peak. Given that the off-peak time is typically only 6h/day and that the heat pumps schedule needs to be able to run most of the day, the average price/kwh used by the heavy pump daily is likely to be around 20p/kwh. Even with a COP of 4 this still equates to 5p/kwh of useful heat. That's a saving of 2.5p/kwh. I use about 1000 litres of oil/year (about 10,000kwh). So my saving would be about £250/year. Even with a grant and assuming my net costs to include a new water tank, several new radiators and plumbing modifications, it would still cost me around £7500 to install a heat pump. This equates to a 30 years break even point!

@SpeakToTheGeekTech 7 күн бұрын
You should never think about it as breaking even, that's not what it's designed to do. If compared to gas, it's about cost comparative to run at standard rates. If you need to replace your heating system, put a heat pump in instead. If you want to reduce your carbon footprint, put a heat pump in instead. But if you want to save money, maybe invest in solar panels and a battery. A heat pump is for heating your home, not earning you a payback, it's the wrong way to look at it.
@nigelcharles511
@nigelcharles511 7 күн бұрын
I take your point totally. Despite the fact that my house is thatched and therefore cannot take solar panels, through lateral thinking I have a lot of solar and batteries. At home I have 21 panels distributed around my property. At a separate off-grid location 1 mile from home I have another 66 panels feeding 52Ahr usable storage. On top of that I have two camping sized trailers each with 30Ah LFP batteries which take energy home. This all keeps two EVs and the house (minus heating) going for about 10 months of the year. At this time of year my electricity statements are about £17/​month of which £15 is the daily charge. My oil boiler is only 5 years old so no need for a change for at least a decade. It is just a shame that it is uneconomic and probably not green for me to change to a heat pump. @@SpeakToTheGeekTech

Hi tech twin. I've got the same unit, interested how it performs over winter. Are you thinking of getting a ESPAltherma to calculate cop on ha? I've thought about wrapping it or spray painting the fan over to make it appear less ugly.

Yes, it’s there to ensure there’s enough volume in the system for the defrost cycle. The defrost cycle takes hot water from inside and so if there’s not enough volume in the system, you end up in a “death spiral” where the defrost cycle robs heat from the house and yet still can’t quite get up to temperature. We have the same due to 10mm microbore upstairs and the UFH downstairs is sub-optimally spaced out. Also helps reduce cycling due to more volume of water in the system to deal with
@Leo99929
@Leo99929 6 күн бұрын
The heat pump requires a minimum free volume of water to do a defrost cycle. For Vaillant I think it's 15L? So if you have TRV's on your radiators, microbore pipe, and/or a small central heating system, then it can have less than 15L available at some times and that can cause issues for the heat pump. My 3 Bed house doesn't need one as long as I don't use TRV's and my radiators are appropriately sized relative to each other and the heat demands of the rooms they're in. Generally, rather than doing the maths to see if it's necessary, or designing the system so that TRV's aren't required, they just shove a 20L volumizer in and then they're certain they'll have no issues with the heat pump defrost. At the cost of reduced SCOP, increased running costs, and increased installation costs. But they're problems for the customer, not the fitter, and most customers don't know this, so they get away with it most of the time. It's generally a good rule of thumb that if they assume you need a volumizer they aren't doing a "proper" thorough system design and installation for you. More a generic one size fits all. Quite often they can just replace a length of the central heating pipe with a wider diameter and that's enough to get the required volume... Or there's also an electric heating element in the heat pump that can be used for defrost, but that uses more power since it can't leverage the system COP.

So Octopus have a centralised design team who produce the system designs for the customers, rather than it being done by the installers. The approach from Octopus is a boiler-plate one, so they pick from a number of set designs and tweak slightly as needed. This helps them keep the costs down and customers (like me) end up with a good solution at a great price. But, of course, if you want something much more customised and perfect then a Heat Geek installation is the way to go, and you'll potentially pay the premium that might entail.

Aha you are in a tricky situation of which tariff is best for the kit you have got! I think you will be fine - your peak rates are going to get used, but remember your heat pump will be at least 3 times as efficient as gas, if not more, meaning even at peak rates it will not cost you more to run. But you can boost your home off-peak and store heat in it like a battery. Tim from Tim & Kat made a video on this if you want the science behind it! (kzbin.info/www/bejne/p2LXinabo92VaK8si=dFqHtt0_s1rSTzwt ). If you really want to reduce your monthly bills though, a home battery is the only option. Charge it off-peak, your heat pump can use it during the day. This is what I do. I think you have the right tariff though overall especially because of the EV which I suspect will use a lot more energy than your heating.

It is important to remember as well that, whilst a gas boiler is typically turned off over night (unless it’s really cold), the heat pump tends to run 24 hours with, perhaps a setback of a couple of degrees. This means that the fabric of the house remains warm and the heat pump is just topping-up the heat that is lost. This is why the heat loss survey is so vitally important. Every room has a radiator that is sized to maintain the desired temperature by replacing just the heat lost to the outside. A temperature sensor in the house feeds back into the system but the external sensor is what does most of the work as the level of heating is set according to the outside temperature so that the heat lost is replaced. I think my surveyor was surprised by how much I knew but I do like to be informed!!

That video on the "thermal coasting" was very good, although this may not work with the Daikin as it does not come with individual room sensors to switch off the heating in the bedrooms overnight, but could work with the new Cosy 6. For it to be really worthwhile to get a heat pump and an EV at this stage, seems that either I should invest in a decent home battery such as the Tesla Powerwall 3, or Givenergy and make use of the overnight rates to charge up the battery, or Octopus are missing a more suitable tariff in their portfolio in-between Cosy and Intelligent Go aimed at both heat pump owners and EV users.

I had an external sensor installed on a north facing wall of garage low down behind a fence to shade from any solar gain. The heat pump is west facing and at times when ambient is 17/18 and sun is out the temperature goes crazy up to 35⁰c etc. The setting to enable the external temperature sensor is part of the installer setup. The annoying thing is when I use Home Assistant integration for Daikin it only reports the temperature in heat pump. Fortunately having checked spot readings the system is using the external sensor and correctly adjusting flow temp . In Home assistant I plot the AccuWeather temperature. Hoping to install an open energy monitor system soon to complete my monitoring as energy readings can only be taken from my controller manually.

They are expanding slowly across the UK. Speaking with someone from Octopus earlier this year, they tell me they are reluctant to do installs too far away from their support bases because they just can't offer the expected level of aftercare otherwise. The bigger they get, the wider they can spread themselves though so hopefully they'll reach Scotland eventually. I was one of the first installs in Wales and they tend to send engineers from Bristol.

You don’t control individual room temps, the radiators are each sized to provide a particular temperature at a given design flow temperature based on the heat loss of the room. The skill of the system designer is far more important with a heat pump than with a gas boiler which is why you have to be so careful choosing an installation company. And the airing cupboard is half height, the floor is waist level! The tank is too physically tall to fit in there. Also you’re not allowed to fit water tanks above stairs anymore under building regs I’ve been told, although I’ve not seen that in writing anywhere.

Could some explain why do you need TVRs if they should be left fully open. Still building up my knowledge base so would welcome some advice.

Honestly I don’t think anyone really knows. It appears to be a leftover requirement in the MCS guidelines that Octopus have to adhere to in order to meet the criteria for the installation to qualify for the government grant. I imagine MCS will slowly evolve the requirements as best practice changes.

Probably the same reason a gas boiler is better on an EPC than a heat pump!! “Heating by electricity” was traditionally less efficient than heating by gas. TRVs are about saving waste by controlling the heating in different rooms but are not beneficial when using a heat pump.

Is it possible to use tado valves with the heat pump? If not, how do you make temperatures even in rooms which are colder? We have a room above the garage and until we fitted tado we had to overheat the other room where the thermostat was in to keep the room above the garage warm enough. Tado 100% fixed that problem. Now we’re on a journey to have the octopus heat pump fitted… I’m a little concerned

It is possible, but you shouldn't do that. You should size the radiator in that room in accordance with the heat loss for that room. Having an even temperature throughout your home is all about sizing the radiators correctly and making sure they are balanced properly.

A positive with a heat pump is that you don’t need any smart controls. As Oliver has commented, the system will (or should be) sized to match the heat output of your radiators to the heat loss in each room. If a specific room is getting a bit too warm then a standard TRV can be notched-down a little bit but, if the system is well designed then this shouldn’t be necessary. I believe they actually work best in more open-plan layouts as there won’t be got and cold spots as the temperature evens out. Watch some of the Heat Geeks videos for information on control and zoning (NOT!) Anyone want to buy a second hand Tado system with 9 radiator valve controllers?

System should be balanced so each room heats correctly using the lock shield valves on the radiators.

If you remove the gas hob and then the gas smart meter, do you still have to pay a gas standing charge? I know someone who went off-grid and still had to pay an electric standing charge to “maintain the existing electricity supply cable”

If you have your gas meter removed, all standing charges also stop.

Yeah you will ruin your property value if you don’t maintain your electrical connection as reestablishing it later can cost thousands. Just export a bit of solar in the summer and it’ll cover the cost and in the winter it’s a pretty good value supply of last resort.

@@SpeakToTheGeekTech Just in case your 'all standing charges' gets misconstrued; all gas standing charges will stop if you remove the gas meter. You will still have to pay your electrical standing charge if you are electrically connected.

​It is very difficult to go totally off-grid in the middle of winter and for most people practically impossible if you have an EV and/or use a heat pump. It is just annoying that they have increased the daily charge so much.

We have the same issue with the gas hob. Will be interested to know what you swap to. Are you likely to go induction? We only recently found out that the hole under the gas hob is actually smaller than the hob itself. We were worried we would need a new counter top. Turns out looks like we won’t.

Definitely going to be induction, but how long it will be until we replace it depends on the advertising revenue from this video :)

I replaced our gas hob with a Bosch 13A induction so just plug into a regular socket. It has 4 rings and we are a family of four. Works absolutely fine for our requirements. Side benefits are a completely flat surface and much better air quality.
