boiler with a difference wiring

[sellers]

I've got to look at a job next week intergrating a woodburning stove into the central heating. The owner is a plumber and has done all the plumbing and currently turns the pump on manually.

I'm thinking of live to a pipe stat to detect the fire being on, then to the motorised valve and pump. Anyone else had any experience of these? wondering if I should add a stat in to shut off the valve incase it gets too hot.

Just remember that if it's convection HW and the HW cyl gets too hot you have to dump the heat from the fire into the CH

Have a look round heatweb.com and build one of their thermal stores with all the options he has. They then give you a wiring layout. An example would be to search for CXC-210-DBKDD-MIMZH and look at the wiring for that as it maybe what you want (solid fuel with overheat protection).

Need a bit more info about the pipe work /cylinder arrangement to give accurate answer...

Did one 18months back with log burner or oil boiler to heat a cylinder..

Then from that hot water, underfloor heat & towel rads.

In this case the wood burner was just gravity flow to water cylinder..

If the cylinder got to hot had a thermostat high up on the cylinder to switch on a pump to dump heat off to the Two bathroom towel radiators..

But there was also a pipe stat on the towel rads in case the towel rads got too hot..

In the event of cylinder & towel rad dump getting too hot think it would then just go off on some pressure relief boil over pipework..

But the lengths of pipe run from log burner & furthest towel rads would allow a lot of heat to be dissipated anyway.

These were in addition to the standard thermostat control for the bog-standard water & underfloor heating to turn on the oil boiler if the log burner not running..

Also the cylinder was a slightly non standard jobbie with two coils inside it..

So really could do with knowing how the plumbers has it connected to the main water/heating system???

Don't know if I'm allowed to advertise on this site ** but I've been doing this for years. My site, goes through the ins and outs and we supply a controller for the electrics. Plumbing is via a neutralizer which we don't supply. Also try the patent office web site for some weird and wonderful solutions.

Cheers. Chris
