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...
Just wondering if anyone has even seen an issue with the pressure gradually increasing on a closed loop system where there is no fill loop attached. I'm seeing this issue on a gshp and whats more unusual is its on the cooling side. If it was on the heating side you could put it down to expansion...
Hi all. I have an Isoflo CL170 cylinder with good few years life left in it in my system which has performed trouble-free other than the odd new immersion element. I'm getting a new ASHP fitted and the installer is recommending scrapping the Isoflo and replacing it with a Secon Trade Heatpump...

The smaller one has solar heating and this then provides cold, warm or hot water to the...
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...

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...
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...
Has anyone installed / worked with air-to-air heat pumps?
I wonder if their running cost is also high?
There’s no information on running cost and even the people handling the funding pots for Air source heat pumps, are not aware of the costing.

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...
I'm building a new house and I have no idea what option to chose for heating/hot water! I've looked at biomass/pellet boilers, electric combi boilers, air source heat pumps and solar panels(combined with an electric boiler) After doing a lot of research (and not understanding some of the...
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 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.

My site is on the side of a hill and the...
