New hot water cylinder future proofed for heat pump?
Hi Forums
I plan to change an old hotwater cylinder now, for a modern un-vented one, with immersion heater I can use with an Eddie and my PV system.
I currently have a reasonably new mains gas system boiler for heating and hotwater.
I plan in next few years to extend and insulate house and hope to fit ASHP at that time when property requirements are known.
Will a cylinder advertised as made to work with ASHP, work with current gas boiler? I assume it will make no difference to cylinder operation if boiler flow temp is set lower, but a plumber I talked to said they where all incompatible...
Help much appreciated
Hi, @Pen-y-Bryn I had exactly the same situation as you and went for a Mixergy Unvented cylinder. It has a conventional heating coil and immersion heater but also has ports to add a heat exchanger for a future heat pump.
In the end I bit the bullet and took out the gas combi and fitted an ASHP before fitting the cylinder, but my original plan was to do as you are considering. I have plumbed things so I can add the heat exchanger but at present just heat my water via an Eddi. I thought I would monitor things to see if it was worth adding the exchanger.
All th details are in my blog, the address is in my signature.
House-2 bed partial stone bungalow, 5kW Samsung Gen 6 ASHP (Self install)
6.9 kWp of PV
5kWh DC coupled battery
