- Morning, Does anybody know what happens to a solar thermal flat panels (a pair on south facing slate roof) that have been unused for at least 12 months possibly year before also. System has been switched of due to loss of pressure. How will last years heat wave conditions have effected the panel components. Is […]
- Is anyone interested in a two butt rain/bathwater/greywater recycling project?
- Calling all plumbing and heating engineers. We are doubling our heatpump installation team across the UK and need plumbers and heating engineers to help decarbonise the UK. You can apply directly on the Octopus website, or you can contact me directly.
- Hi. Hopefully someone can point me in the right direction. Bit general. We have solar boosting our hot water using iboost. My question, the current immersion element hasn’t been changed for 14 years. Should I upgrade/change it to increase efficiency? Current I haven’t seen any degradation in use. Thanks
- Hello My solar thermal system appears to be leaking fluid (pics attached). Could anyone give me an indication of what the issue is likely to be and the potential cost to rectify? The system was installed in May 2021 and has a flat plate panel on the roof. It works very well generally and between […]
- Hi, Solar thermal not so big these days but a couple of Q for anyone who still works in it. Background. I'm an Electrician not a plumber.. I've been maintaining my otherwise excellent solar thermal (Original install MCS by Others), for the last ~ 18 years, over which time I've needed to clean and flush […]
- Heat pumps are starting to look like a conspiracy against the public British Gas has just thrown a large spanner into a policy that seems increasingly unworkable, costly and embarrassing for the Government www.telegraph.co.uk I realise not many have a sub to Telegraph (neither do I) but this is the article in full. As for […]
- Hello, So I want to add a solar thermal system to my existing Worcester bosch greenstar but don't want to lose the functional benefits of the combi boiler. I'm proposing to install the solar collector on the side of the house in a position that will enable gravity flow to a 200litre tank just above […]
- I'm planning to get an air source heat pump (ASHP) installed and I'm considering my options about the location of the water cylinder as I live in a small house and space is a premium. I was thinking about building a small insulated shed about 20 to 25 metres away from the house to put […]
- We are installing solar power irrigation systems for smallholding farmers in Rural Ghana, We have 12V DC 0.18kW (max 20A) pumps, there only power source will be a voltage varying from 15-20V coming from solar panels. The boreholes are narrow, therefore is not much room for a float switch, The max flow is 20 Litres […]

- Hi all Are there any Windhager Biowin2 experts who can help me to understand what this means? I’m fairly sure mine doesn’t have such a mixing valve and not sure what or why one is required. I’d like to understand before trying to find someone to install what the original installers omitted 8 years ago. […]
- Hello all, I should start off by stating that I'm not in the industry – I'm just a DIYer with a "what-if" idea. Hybrid systems and solar diverters are nothing new, but as far as I can see the current hybrid systems all require a change of boiler and I'm going to propose a system […]
- Helping to audit an electric-only house with ASHps -NIBE kit installed into the new house in 2012. 2 ASHPs outside -each F2015. I put on some monitoring of their electrical usage -each takes 40W night and day 24/7. It's August so they are off 99% of the time: but when off, still use 40W! 40W […]
- Hello, I hope somebody may be able to help. I have a ecodan heat pump system and have no hot water. The controls are set correct but the light for the boiler is blue. Anyone know what I’m going wrong please? Thank you!!
- Hi, Our church is consdering replacing our old gas boilers with modern condensing ones. We would like a hybrid system involving the use of an ASHP. Two of the contractors that have supplied quotes for the work have suggested that we wait for a while on the ASHP as the prices are falling. The other […]
- Hi all, my parents have had an air source heat pump installed a couple of years ago and have recently started undergoing refurbishing the house and have had several radiators removed and repositioned, can anyone help with regards to how to top up the system as I know that it has to have a glycol […]
- Hi all. Does anyone know of a small water heat system that I can attach directly to the back of my log burner, in my living room, that can conduct the heat (by contact) of the log burner and flow the hot water to a panel radiator in another room (e.g. conservatory)? I only want […]
- What are the factors that determine the life of a water tank? Obviously the quality of the water and the materials used to construct the tank are important. But beyond that I'm fuzzy. Is it just the number of gallons of water that pass through it? The number of "fresh" gallons of water that pass […]
