It’s a balance, and trying to figure out that balance is the hardest. At the moment we’re on a flat electricity rate. I’m hoping to get PVs in soon so this could benefit us. I guess I need to get my excel sheet out and do the calculations.

Well it was a debate whether to install one or not. The original design didn’t have it but that was designed almost 3 years ago. We only just commissioned the whole thing. We’re trying to see what works best. And yes we have very thick concrete slabs.

Correct, i apologies for my poorly written questions

Aiming to minimise electricity bills.

Hey, which is the most efficient way to run a 14kW ASHP. Times intervals or constantly on? 1. We have one specific for DHW the water remains pretty warm for 24hrs (although my husband tends to drain out all the water when he has a shower 🤦🏽‍♀️) 2. We have another one for UFH, no buffer tank. New build, well insulated.

Yes places like big Mat are great!

Thanks! I’ve tried but the country is so backwards, the architect laughed at me when I told him I wanted to put in insulation. We used high density polystyrene boards. re kitchens, they have advanced

Thanks so much for your valuable input. It’s a large residential house, with a home office. Occupancy roughly 4 person. Yes, the heat pump has already been purchased. We aren’t restricted with roof space. I don’t have the calculations at hand I’d have to ask the supplier. Yes we are in Malta, which I would say our winter matches UK’s summer plus humidity.

Absolutely correct! But since ours is a new build we’ve heavily insulated our house and used bricks for the internal skin. In summer we have ceiling fans, house is very well ventilated and will use supplement with the Air Conditioners. Yup electricity bills are extortionate, which is why we went for UFH in the winter opposed to the air heating.

I’ve got a new build with wet UFH supplied by an 14Kw ASHP, we’re in the final stages of commissioning the whole thing. Despite being designed without a buffer tank, now our supplier is now recommending we install a buffer tank. I’m considering perhaps a Solar Thermal collector would be a better option? Any thoughts on this?
