Zoning systems

[Matt0029]

Has the thoughts on zoning systems now changed especially with heat pumps. As we need the free volume area to stop the compressor cycling. Also if zone rooms/areas we are increasing heat loss to that area? Thanks for your thoughts

Open zone on ashp to get maximum efficiency

As for zoning eg upstairs and down you don’t increase the Heatloss you just increase the demand eg downstairs will temper upstairs eg if downstairs is 20 upstairs will be around 18 if not heated

Generally, I've been putting buffer tanks on the heating side. Helps maintain the system while the heat pump goes through the defrost cycle. Also useful if you get a heavy HWS demand and the heat pump is busy charging the cylinder.
