Solar panels can heat water through two main systems: solar thermal panels and photovoltaic (PV) panels with an immersion heater. Here's how each works: 1. Solar Thermal Panels (Solar Water Heating) These are specifically designed to heat water: Structure: Solar thermal panels consist of tubes or plates that absorb sunlight. A heat transfer fluid (usually a mixture of water and antifreeze) circulates through the system. Process: 1. The panels absorb sunlight, heating the fluid inside them. 2. The heated fluid is pumped to a heat exchanger in a hot water cylinder. 3. The heat exchanger transfers the heat from the fluid to the water in the cylinder. 4. The cooled fluid returns to the panels to be reheated. Result: The water in the hot water cylinder is warmed for use in showers, taps, or central heating. 2. Photovoltaic (PV) Panels with Immersion Heater PV panels generate electricity that can be used to power an immersion heater in a water tank: Process: 1. PV panels convert sunlight into electricity. 2. The electricity is directed to an immersion heater inside the water tank. 3. The immersion heater uses the electricity to heat the water directly. Benefit: This method allows PV panels to provide both electricity and hot water, but it's less efficient for heating water compared to solar thermal systems. Comparison: Solar Thermal: Direct heating, more efficient for hot water, but limited to that purpose. PV with Immersion Heater: Versatile (can power other appliances), but less efficient for water heating. In both cases, a backup heating system (like a boiler) is often included for cloudy days or high demand. The Ariston Kairos Thermo HF-2 200-1 TR is a solar thermal system designed for domestic hot water production. It operates on the natural circulation (thermosiphon) principle, where the movement of the heat transfer fluid is driven by temperature differences, eliminating the need for mechanical pumps. Key Features: Capacity: Equipped with a 200-liter storage tank, suitable for medium to large households. Collector: Includes a single high-efficiency solar collector with a gross area of 2.2 m², designed to maximize solar energy absorption. Installation: The "TR" designation indicates that this model is intended for flat roof or ground installations, providing flexibility based on building design and space availability. Durability: Features a 4 mm thick tempered glass cover tested for hail resistance, ensuring robustness against various weather conditions. Efficiency: The system is designed to optimize hot water production even under low solar radiation conditions, ensuring consistent performance throughout the year. This system is an efficient and eco-friendly solution for meeting domestic hot water needs, leveraging solar energy to reduce reliance on conventional energy sources.

Can I switch this burner to work with diesel and what i need please 🙏🏻

Great video . Always love this channel for common faults like this , a video running the ds40 through it would be good

Great sheet mate, can i get a copy and how?

Interesting about the debris in the combustion chamber catching fire with a wire brush, not heard that before. You would think if it was flammable then when the boiler is fired it would ignite anything at that point. Urban legend maybe?

Check the tmv

What do you do need to do if the dial is at the end of the red. And what does it mean?

These are awful. Unfortunately I've worked on a lot of them. The heat exchanger gets scaled up, if you don't descale them regularly it will keep happening. You have to isolate the main taken bottom left then connect your machine from the non-return valve and disconnect it at the top and connect there. Manual describes how to do it.

I grew up in Tottenham too , working at 15 at my dad's commercial heating company ( UHM ) at the top end of BlackBoy Lane . Still a commercial engineer now at 57 .

They are a nightmare for the heat exchanger scaleing up , I'm not keen on these units

It needs tub of ds40 to run through for 1hour , neutralise drain and good as new

I diagnosed this issue as a blocked heat exchanger, and after advising the client to have it cleaned, the problem was resolved. I've noticed that these units can quickly develop blockages in the heat exchanger, particularly when the system's water hasn't been treated. In this case, I was aiming for a "gold medal" or a bit of recognition, as I wasn’t entirely certain of the diagnosis at the time. Unfortunately, acknowledgment doesn’t always come when you get it right-but when you get it wrong, you’ll definitely hear about it.

Hi, what is the efficiency of the panel? Does it at least warm the water in partially cloudy weather? I don't expect it to work when it is full cloudy but is it something like a photovoltaic panel?

The typical van insurance excess in the UK can vary depending on the insurer, the type of van, and the driver’s profile. Here’s a general guide: Compulsory Excess Set by the insurer and mandatory for all policies. Range: £250-£500 for standard vans. It may be higher for young or inexperienced drivers, sometimes exceeding £1,000. Voluntary Excess Chosen by you when purchasing the policy. Range: £0-£500, though higher options may be available. Selecting a higher voluntary excess usually reduces your premium but increases your out-of-pocket cost in the event of a claim. Combined Excess Total excess is the sum of compulsory and voluntary excess. Example: £300 (compulsory) + £200 (voluntary) = £500 total. Special Cases Young/Inexperienced Drivers: Excess may start at £750 or more due to increased risk. High-Value Vans: Excess for claims involving luxury or specialist vans can be significantly higher, sometimes over £1,000. Windscreen Claims: Excess is typically lower, around £50-£100, or even waived with certain comprehensive policies. Tips for Managing Van Excess Check Policy Details: Different policies have varying excess amounts for different types of claims (e.g., theft, accidental damage). Excess Protection Insurance: Consider this add-on to reclaim the excess amount after a claim. Compare Policies: Lower premiums may come with higher excess, so balance affordability with practicality. Always confirm the specific excess amounts with your insurer before purchasing a policy.

Yes.....a power bank has saved me a few times ...when I remember to charge it 😂😂😂

Anyone not taking the case off a boiler is not servicing but robbing a living, I would sack anyone I found not taking the case is a boiler

Yes usually to top up analyser and printer or tablet

It's one of the mucky parts of our job but it helps pay the bills.

Things to Know About Power Banks 1. Capacity and Charging Power: Measured in milliamp-hours (mAh); larger capacity means more charges for your devices. Ensure compatibility with your device’s charging requirements (e.g., fast charging support). 2. Port Options: Check the number and type of ports (USB-A, USB-C). USB-C is faster and more versatile. Look for power banks with multiple ports for charging several devices at once. 3. Size and Portability: Higher capacity power banks are bulkier; choose one that balances portability with charging needs. Consider lightweight models for travel. 4.

Charging Time: Some power banks take hours to recharge. Models with fast input (e.g., USB-C PD) recharge faster. Solar-powered or wireless charging models are convenient but often slower. 6. Battery Type: Lithium-ion is common for affordability and energy density. Lithium-polymer is slimmer and more durable but usually more expensive. 7. Lifespan: Measured in charge cycles (typically 300-500 cycles). Avoid overcharging to extend life. 8. Additional Features: Some power banks have built-in cables, flashlights, or wireless charging pads. Water-resistant or rugged models are available for outdoor use.

Unblocking a toilet can be straightforward or tricky depending on the severity of the blockage. Here are some effective tips and tricks to help: 1. Use a Plunger Type of Plunger: Opt for a flange plunger; it's designed specifically for toilets. Technique: 1. Ensure there's enough water in the bowl to cover the plunger head. 2. Place the plunger over the hole and push down gently to create a seal. 3. Use forceful, steady plunging motions. 4. Repeat several times, then flush to see if the blockage clears. 2. Dish Soap and Hot Water Pour 1/4 cup of dish soap into the bowl. Follow with a bucket of hot (not boiling) water poured from waist height. Let it sit for 10-15 minutes to loosen the blockage, then try flushing. 3. Homemade Drain Cleaner Mix 1 cup of baking soda and 2 cups of vinegar. Pour it into the bowl and let it fizz for 20-30 minutes. Flush with hot water. 4. Toilet Auger or Drain Snake Insert the auger into the bowl and crank it to break up or pull out the blockage. These are especially useful for tougher clogs deeper in the pipes. 5. Vacuum (Wet/Dry Shop Vac) Use a wet/dry vacuum to suck out the blockage. Remove any attachments and cover the hose with a cloth for a good seal around the toilet hole. 6. Enzymatic Drain Cleaners Use enzymatic cleaners designed for toilets (available at hardware stores). These break down organic material but may require several hours to work. 7. Wire Coat Hanger Straighten a wire hanger and wrap one end with a cloth to prevent scratching. Insert it gently into the toilet and move it around to dislodge the blockage. 8. Adjust Water Levels If the bowl is too full, remove some water using a bucket or cup before trying any method. 9. Flush Properly Avoid repeated flushing if the bowl is already full, as this can cause overflow. 10. Call a drainage specialist (If Needed) If none of these methods work, the blockage might be further down the line and require professional tools to resolve. Preventative Tips Avoid flushing non-flushable items like wipes, sanitary products, or excessive toilet paper. Regularly clean and maintain the toilet with mild cleaners to prevent build-up.

That little sticker/ tap sticking out of the the burner is a tell tail sign it hasn't been apart many times if at all ?, also intermittently locking out is likely the ignition transformer
