Things didn't quite go to plan with the install... They can't start this week, but rather next week, so that's a whole extra week without heating. We'...
@alec-morrow Yes the boiler is completely shot, so no point doing a step-by-step change at this point. The installers have confirmed that they'll b...

It does sound quite ambitious, but I think it should be fine so long as you take measures to protect yourselves. What happens to the deposit if the ...
The results are in, and using a calorific value of 39.5 (my meter is in m3) and a flow temp of 70C, it started on about 18kW of gas usage, then settle...
28mm pipe can carry 16.8kW of power if the difference in temperature between flow and return is 5C, which it probably is. This means that assuming the...
That's exactly it. I fear that in the ASHP world, if you don't know at least as much as the person selling you it (assuming they're a sales person), y...
I appreciate the vote of confidence! However, I don't think I dare go outside of MCS installations because it gives me recourse if something goes wron...
I guess this is true, but it depends how well the heatpump can modulate its compressor/flow rate. Most, it would appear to me, do not modulate all tha...
