Advise on heating controls

    Considering upgrading heating controls and looking for some advise.

    Current setup is an old gas boiler that heats radiators and hot water cylinder. Setup as a single loop but can manually close a valve to heat just the hot water cylinder. Have the climote system to control when the boiler switches on and off and TRVs on most of the rads.

    Was considering getting a plumber to split the house into a number of zones particularly the hot water cyclinder. However as it is an old house about 90 years wasn't sure how feasible or expensive this would be.

    However while I was searching for heating controls I came across these wireless controlled radiator valves.

    Has anyone got any experience with these?
    What are the advantages and disadvantages compared to a zonal heating system?
    Are there any installers in ireland for these products?

    Is your heating system 90 years old?

    No think it is about 15 to 20 years old.

    WIth those remote TRVs, you will still be heating a lot of the pipework around the house. Your idea of doing zone valves would probably be more energy efficient. Plus you already have the climote, so just control off it.

    There is a grant to do this type of work from SEAI, and certainly their spec is a good standard to work to also:

    If there is a manual valve to control the hot water cylinder, you can certainly get the manual valve replaced with an actuator. You would have to run a wire from the boiler up to wherever the valve would go.

    You need to consider changing your boiler while you are at it. 20 years is just too old. It will fail on you at some stage and then you will have to do everything in a big hurry.

    I would certainly think that the TRV's would be a good enough solution. You lose some heat, sure, but it really isn't that big a deal and there are benefits too.
