Linking UFH to my Systemate 2000???

Hi All,

We want to link an underfloor heating system into our current heating system. We have an Ideal classic heating only boiler linked to a Gledhill Systemate 2000 on out top floor. We want to our UFH and hot water and radiators to run independently of each other. Can this be done? If so, how, from an electrics perspective?

Any help would be greatly appreciated.

Anything can be dun, all depending on the amount of money you have in mind to do this. If you go for electric UFH, this would be complete independent from any other of your existing systems. If you want to go with a wet system (linked to your SM2000) you have to run the UFH with a separate Pump, controlled from a separate thermostat and a motor valve. All depending on the aria you like to fit UFH in to, or if you would rebuild from radiators to UFH. Difficult to say without an inspection of the existing and the plan you have in mind.

Thanks Mario I appreciate your response. It is a wet UFH system. We live in a 3 storey house and have extended the ground floor. The UFH would be on the ground floor only. We would move our current thermo for rads (on ground floor now) to the 1st floor. I believe, currently, our systemate 2000 pumps start as soon as the boiler fires up, is this because it is the systemate currently calling the boiler the fire up? When we link in the separated wet UFH system to the flow and return from the boiler, obviously we want to know that when the UFH calls for the boiler to fire up, that it does not start the pumps in the S2000????

This is a bit more complicated as you may think, the Gas Boiler on your System is the charger for your SM2000 and also supports the heating via the port valve on the SM. So, in fact you can not connect the UFH direct to your Gas Boiler. You have to connect to the SM via a port valve, before the radiator feed. (This splits the radiators and the ufh feed) Then you need a second Pump for the UFH , and this has to connect also to the SM heating call to provide heat to the hating feed pip work but blocking the feed to the radiators or opening this as well to feed both ( radiators and UFH). The UFH feed also has to be blended down in terms of temperature with the return from the radiators as the Radiators need 60C flow and the UFH max 40C. This is a lot of Pipe work change and fiddling, ok if you rebuild a complete system from scratch, but complicated if you try to ad on. Also for an economic run of a correct installed UFH, you have to have 10 cm concrete above ( and of course 10 cm insulation below) your UFH pipe work (works as heat storage to make the UFH efficient).
Hope this helps a bit
Kind regards Master Mario

Many many thanks Mario.
