I haven't had any other paper work since moving in - What would be on it? That's good to know. Does all the settings and temperatures look to be normal then? I'll change the heating schedule so that it is similar to yours and see if that helps the heating in the evening

It's a 305L and 130L buffer tank. I noticed this question had been answered "YES' on my MCS Compliance Certification but none had ever been explained 'Have the implications of the system design on the costs associated with providing space heating and domestic hot water to the building been explained in writing to the owner?' Going by their calculations around about £4 is about right The Newlec 7 day programmer to the right hand side of the ASHP controller is some how connected to the thermostat wiring centre so it is set to 'Always On' as I was told it's best to keep the UFH on 24/7.

Most likely an off the cuff statement from the builders to me as to why the MVHR was needed. The mixer at the manifold is set at 53/54 (You're right - Pressure gauge on the right) The last picture of the controller is saying the Tank is at 50°c so does that mean that is the supply temp to the UFH? Would I be right in thinking the bigger of the two tanks is the DHW and the smaller is for the UFH? My other question regarding the timing - If anyone has any knowledge of the controller does it have a set desired temperature that will shut off the heat pump when it's reached. Currently my electric bill is roughly £5 per day but I'm unsure if this is good or not. My temperature settings are in red settings below

Since I moved into my new build no one has ever explained how my heating system works and the settings have been left unchanged since it was commissioned. I'm finding that in the evening the heating can take over an hour to go up by 1° and sometimes struggles at all to get up to temperature at all and can drop below the low threshold. Each zone in the house is set to 22° and is set to always on. Im using a Panasonic Heatpump WH-MDC12G6E5 (I have been told this system is overkill for the size of house- 169m2 Detached bungalow) There is also a Paul MVHR system installed due to being a passive house which I thought was maybe causing the system to go below the low threshold but on turning it off the heating drops further and rises sharply when turned back on. My query is everything Ok with the controller settings and set up as a whole. The timer is set to come on 0600 - 1400 each day and then off the rest of the day. Is the temperatures displayed on the controller optimal? Ill upload some photos of my setup and some settings - Any info at all would be greatful.
