Is anyone interested in a two butt rain/bathwater/greywater recycling project?
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...
Hi
Can somebody tell me if a standard heat source pump installation uses a pressurized hot water tank? Or will the pressure for the hot water be the same as with my oil boiler and water storage tank (gravity-fed)?
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...
Hello

In my new high efficiency house, I will have UFH with an Air to Water (A2W). Heat pump Monobloc, but for extra cooling on hot days I think extra air cooling with FCUs is needed:
Should I use a secondary Air (to coolant) to Air system, or stick with just the Air to Water system to also drive my...
Hello All, newbie here.
I am building a new home on a spacious plot and considering a ground source heat pump instead of air source.
I understand trenches need to be 1.2m deep, 1m wide, and 5m apart.
But how level does the overall site have to be?
My site is on the side of a hill and the...
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 the...

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...
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 which could use...
Helping to audit an electric-only house with ASHps -NIBE kit installed into the new house in 2012.
2 ASHPs outside -each F2015.
