Please could the heating engineers/plumbers in the trade give me an idea of how much to budget for an upgrade to the controls on my central heating system?
The system is a fully pumped, open vent system controlled by a simple two channel timer (Honeywell ST699). There are no rooms stats, no TRVs on the radiators and no cylinder stat on the DHW cylinder.
I wanted to:
- Replace the ST699 is a Honeywell CM907 (at the same position as the ST699)
- Add six TRVs to the radiators in the other rooms
- Add a cylinder stat
- Add an outdoor temperature sensor for weather compensation
I would propose to supply the CM907/TRVs/outdoor temp sensor/cylinder stat, and have the engineer supply all the other materials (fittings/cables/etc.)
Can you give me an idea how much this should cost including the labour to install everything (but excluding the parts I'm going to supply)? I'm in South Yorkshire.
Many thanks
