The outside temperature has definitely helped the house temperature- but the readings are showing , that the raising of the flow rates and lowering of the flow temperature has helped the energy consumption of the unit. The flow temperature is currently set to 35c. The house isn’t feeling cold either. I’m not using a timer and just have the thermostat set to 22 for the kitchen and 21 for the bedroom Thank you for your help, it’s much appreciated

I have increased the flow rates to as close as 2.5 as I can. One bedroom can’t go that high as it loosens too much and pops in the air so fluid goes everywhere. From looking at the smart meter- having the flow temp on 35 compared to 44-45 doesn’t seem to be much less in KW and if it doesn’t heat up the house as much and had to be on longer It won’t be as effective . Maybe as mine is all electric with no gas and radiators it’s different to yours? Will see what the pump says in 5 days time and post my findings Thanks for your help

Wow! That’s quite amazing. I will have to change How my zones are setup then. How have you set yours up? As this is how it’s setup for the kitchen, lounge , utility area as its setup on the one zone on my Heatmiser app. Have also attached a heat graph ( the kitchen warms up when the sun is out due to the glass ) and the estimated consumed energy summary from my Mitsubishi App for the last 5 days. Your help is really appreciated

Thank you for your replies. Currently I’m running it more like a conventional heating. on 3 hours in the early morning and 4 hours in the afternoon for it to warm up when we arrive back home. When a Mitsubishi engineer came out he was surprised at how efficient it all was- as it was reading 3.8? If I had the pump on all the time, wouldn’t it cost me more electricity/money? I don’t know the pipe spacing but I do have this from the installation company . When I tried a lower temperature the house wasn’t warm enough

Hi Everyone, Hoping you can offer some guidance. I’ve just built a Barn with Heatmiser underfloor heating everywhere (no radiators) . All powered by an source heat pump. I have the length of my pipes and currently all the flow rates are set by default to 1.5. ( for the house to not feel chilly the flow temp needs to be at 44-46, was on 50 the other day when we were at -5/-7) I have read up about the loop length needing to be divided by 40 to a obtain the flow rates, I was just wondering if that’s set in stone for all types of floor etc or should I be having less or more flow rates dependant on the floor type? ( As I have three rooms that are carpet, bathrooms are tiles and everywhere else is concrete floor.) And does it matter how far away the room is from the plant room? Thanks for your help
