Hi anyone here any experience of using this system?
Have it months
Not impressed too much tbh.
Hard to work out how to run it economically.
Some experts ( 
you tube variety)
Recommend keeping it on all the time,
This kinda goes against the grain.
Badly miss the open fire,
But bought a 12 litre dehumidifier during the week to dry the laundry,
Impressive tbh.
Thank you
Have you solar? Don’t think it makes much sense otherwise
No
Effing green policies
I’m getting the solar shortly. The air to water makes sense with it I think. We have gas here and the house is well insulated so its not a slam dunk. I would be tempted to make the fire gas but the standing orders make that stupid option because you would rarely light it. Might light a plastic bonfire in front of the air to water inlet on cold days.
Got new doors: windows
Loft insulated with natural fibres
House is warmer but the heat is minimal tbh
Normally u have to change all windows and replace external doors or your fan outside will be working overtime to replace lost heat
We’d no choice
Gas was taken out
As were the fire opening blocked up
You got a free retrofit of your house?
Yep, have one with 5 years, no solar panels. They are expensive but no more than if you were running an oil boiler. The difference is that you end up paying what you’d pay for oil but to your electricity supplier.
Solar definitely helps I’d say but it’s at a considerable additional cost.
Have you thermostats in each room or have you zones? It helps to set the temps of the hot/cold water on the master unit too (you’ll need technician access to change this).
You do need to leave it on, it goes against reasoning but it is the case, if you turn it on and off… it will cost you a fortune…
I have both but the electric bill is still 400 a month. The electrician I used has been absolutely awful though so I wouldn’t be at all surprised if it’s not connected properly. I’m having to get someone else in to fix all the mistakes.
Underfloor? I know for bigger houses air to water can’t handle the size.
Did you try Aluminium rads? We fitted them, we didn’t go for underfloor but the aluminium rads work really well… heat dissipates really well from them… always just hand warm when on but never hot.
We were told by our plumber that the metal rads took serious energy to get them hot and then didn’t heat rooms that well
Yes underfloor but there’s two pumps afaik. It’ll be cheaper in the summer no doubt, but we’ve lots of PV panels, and a battery (2), and the electricity bill is very high. Without the government rebate it will work out at 4k pa. There’s only electricity going into the house, no gas, but that’s only 3 people
The underfloor is expensive. You can’t boost it when its cold. It takes ages to react. Leave it at temperature that’s comfortable and live with it.
It’s fincky. If you light a fire it will mess it up. The thermostat in the room will knock off. And then it will kick in later and it doesn’t do good like that. It needs to be a temperature all the time
We do up it when it’s cold. It has been very cold. The house is AAA rated though.
Upping it does nothing. Have you noticed that? Takes a day to kick in. Leave the thermostat constant would be my advice. And don’t light a fire.
What temp have you the thermostats set at?
To be honest, we don’t have underfloor but it does take time to react to a dip in temp… the first winter we kept turning it up and down and the electric bill nearly broke us
