Heat Pumps: anyone have one/thought about it?

I didn't think putting the tank in the loft would be recommended? Our loft is effectively always at outside air temperature thanks to the insulation doing its job and keeping the heat in the house - so a hot water tank sat at nearly 0ºC ambient temperature seems a little... inefficient?
The Vaillant tank is very well insulated. It's definitely not ideal from an overall efficiency perspective, but really the leakage to ambient is not that much and was worth it to free up space. All I have in the house is a manifold behind a false panel in the cupboard. So far performance of the system has been very good. House is comfortable all the time and we seem to be using about 13kw per day in the current weather.
 
You have the hot water problem as well. In hard water areas immersion heaters tend to be somewhat unreliable compared to proper heating coils in the long term. The ideal solution would be a proper hybrid A2A/A2W system where the outdoor unit could be connected to FCUs and to a wet system, but this still doesn't really exist.

You can do it in part with something like the Daikin Multi+ system, but the offered hot water tanks are pretty tiny for a house, and it still doesn't do any wet space heating anyway. When we went A2A we just kept the gas boiler too.

My loft setup at 4am this morning.

Thankfully there are isolation valves on both sides of each of those pipes in that area so it was very quick to stop once it woke me up and I got up there.

Hello everyone! Can someone explain to me if I am right or not. Planning to renovate heating system and install heat pump. From indoor unit to outdoor unit pipe length is about 6m. Originally units have 1/4 and 1/2 connection, but after reading manual looks like I need to change 1/4 pipe to 3/8. There's factory supplied adapters from 1/4 to 3/8. With original connectors after installation there's totally 6! places where pipe is connected. Any experience with that?

I have my survey on the 9th kinda looking forward to see what they suggest, starting to hate the noise of the boiler when it starts up in the morning.
Best of luck. I have 4m between me and next door and the surveyor still couldn't find a unit that passed the noise test.
