So if I am getting a "all-in-one" heatpump system liek Vaillant uniTOWER or even teh Daikin alternative am I "doomed" with an inefficient cilinder? Or are they feirly inefficient ? If so? which of the brands that offers "all-in-one" heatpump system has teh best (larg heat exchanger) cilinder?
@mooobymoof 7 сағат бұрын
the best would be a circulation pump that changes speed based on heating need

Hi, We’ve had a grant 17kw heat pump and water tank fitted along with solar via ECO4 grant and they have to fit a Honeywell stat/controller. Can this be replaced with a Hive smart stat and controller? Not that it matters but ours is also a retro fit into a 400 yr old farm cottage.

You could also acheive this with a relay. Take the switch live of hw to feed relay, the normally closed contacts of the relay interupt the switch live of the room stat. So when hw is on it opens the supply to the room stat.

When you replace the blending valve why is non fixed better? Why would you want to change the blended temperature automatically? If you set the mixing valve to a maximum e.g 45 and let the boiler pick the temperature it will provide, e.g 40 then what effect would using the electronic valve you showed have? I am not a plumber so maybe I am missing something but I am just trying to understand the best setup. Thanks
@UrbanPlumbers Күн бұрын
@@bsm8444 because with the blending valve the boiler will now modulate to the lowest possible flow allowing for much higher system efficiency. Also not running more flow temp into your UFH makes the systems also waaay more comfortable for the user.

My plumber put in a hive thermostat for all the rads and heatmiser thermostats for room UFH even though the boiler was a Vailant ecoTec 635. When I asked him about the Vailant controls he said it wasn't suitable but it looks like he just didn't want to learn. This setup looks great, and actually makes use of the features the Vailant boiler has. I see you are based in Surrey which is not too far away from me. Might give you call!

Valliant confirmed to me that the ecotec already supports PDHW so why is there a need for the diverter valve?
@UrbanPlumbers 2 күн бұрын
yes it does support PDHW (Which most boilers on the market don't) - so it means you can run DHW at one output and flow temp and then heating at a different output and temperature again - but it still requires not only external diverter valve, but also separation, mixing vales for UFH and controls. Some boilers may have internal diverters, such as Vaillant Green IQ 627 or Viessmann 200. In Europe most vaillant boilers will have internal diverter. Not in the UK, as UK is some 30 years behind Europe.

You can’t stop the clacks and clicks. It drives me nuts. But I had a vaillant engineer come out just the other day. He said it’s not the boiler it’s the pipes. I strongly disagree. It’s in the boiler. Strangely enough it was dead quiet when he approached the boiler. He did hear a click but he says it’s normal. As soon as he left my property the thing was clacking away, and even worse than before. Best to live with it guys. No matter how angry it makes us.

@UrbanPlumbers 6 күн бұрын
Mitsubishi has very poor and dated controls, also pricey for really old tech. NIBE has appalling customer service. More and more installers are dropping them as there is no backup. Old r32 units are noisy and expensive. New r290 is ridiculously huge. Panasonic may be worth looking at. Vaillant ticks all boxes: decent unit, ok controls, good backup, decent price compared to NIBE and Mitsi - it is just overall much better value than other companies.
@ReneArtoisMr 6 күн бұрын
@ Both LG and Panasonic launched new R290 units. What do you mean by ‘no backup’ from Nibe, while the customer support is appealing? The price point from Vaillant is indeed attractive. Their controls also support Opentherm. But their VWL 105/6A is so big and its minimum output is so high. Nibe is indeed expensive, so is Mitsubishi and Daikin

@tommyhendry8771 7 күн бұрын
Between your content and Heat Geeks I have learnt so much. I am a little confused by flow rates though. I understand the maths but could swear I heard on Heat Geek that if you increase the overall flow rate you can reduce the flow temperature? Is that right? If so, why not open the valves on the manifold fully and reduce the flow temp? I get that increasing flow reduces delta T but does that really matter? For example, if you used a delta t of 5 instead of 7 then your flow rate would be higher and so could reduce the flow temp or am I missing something very obvious?
@UrbanPlumbers 6 күн бұрын
Yes you are confusing MWT with flow temp - no matter the flow rate flow temp stays the same. MWT increases with flow and DT narrows. Revisit mass flow equation. Flow = power / DT * SHC
@tommyhendry8771 6 күн бұрын
Ah I see. I guess I assumed a higher MWT would mean more heat released into the room but as you can't increase the flow rate without it decreasing the delta T you'll always have the same power output. I guess the question then becomes what is more efficient for a heat pump. Does it use more electricity to pump at a higher flow rate or overcome the flow temperature drop from a bigger delta T?

Nothing wrong with that 11 kW heat pump. It will just switch on occasionally, whereas a small heart pump would need to run much longer, wearing out faster. And this one is a quality brand, with a Japanese instead of a Chinese compressor. It will last long, as it hardly ever needs to run on peak performance. I wouldn't change it. A bigger concern would be weather exposure. I would put some sort of roof over it against rain and snow and some provision against direct sunlight baking against it in summer.

I just had our buffer re-piped to be a volumiser, so it's now a single loop system. Efficiency increased, but only from horrible to "meh". We also have a Vaillant aerotherm plus, just the "7kW" unit. They set the building pump from "auto" to 50%, which is the lowest option. The lockshield valves on the radiators were mostly open and the flow rate was around 990l/h, which we figured was probably still too much as we still had low dT of <1.5K. Now we are trying it out with the flow rate reduced physically by having turned down the lockshield valves significantly on all rads (~1/8 turn open). This way I can easily bring down the flow rate, e.g. to 650l/h which the installer now says would be right for our house. However, I am wondering if this could put stress on the building pump of the ASHP? The specs say min 540l/h, so does that mean it's OK?
@UrbanPlumbers 10 күн бұрын
Put the pump in auto and don’t throttle the flow. Your narrow DT suggest a hugely oversized unit or zoned system. Throttling the flow will only make it worse. Let it run at DT1.5 - nothing you can do about it and throttling will not help with anything - only a smaller unit will

@UrbanPlumbers of course you would say that. But the video sais the new system is not cheaper. Ultimately, putting all your eggs in one basket might seem like a good idea when doing it but usually is not. I agree and understand the concept of simple is better but the fact remains that the most vulnerable parts in the modern boilers/systems are the electronics and are the most costly to replace you starred the video with " it's a dumb boiler-it's told to fire and it fires..." I personally don't see anything wrong with such arrangement and if there is no cost benefit to change it - don't change it (if it's not broken - don't "fox" it). As doe the pipe work sizes. Yes indeed the smaller sizes create problems with the ease of flow and so on as well as obviously the thermal emisivity levels but I have never heard of anyone using 12mm pipework as standard unless its a retrofit and there are restrictions on the height to be considered. There is no such a thing as "one size fits all" so giving partial information and opinion based on it is not a good practice I believe.

I like the way you concentrate on making it as simple as possible, and removing as many single point failing points as you can.
