Hi guys, first post.
I'm renovating an old house, it had a back boiler heating a DHW tank in the loft, direct. I replaced it with an (uncontrolled) stove and a proper lagged indirect coil tank, with a seperate feed and expansion tank.
Now I've also put in a pumped radiator circuit and planned to connect this to the existing gravity circuit using one of those "dunsley neutraliser" header boxes. With a thermostat so that the return to the stove has to be hot before the radiators start, simple stuff.
OK so far?
Then I discovered I actually have mains gas (doh!) so now want to put in a boiler. I picked up a second hand glow-worm 18 HX (for vented systems) on ebay.
I think I can connect this to the dunsley header with its own pump, partial injection to the tank coil, to get heating and hot water from either source.
And I want the boiler to go in the loft, ideally.
But I'm having a bit of a crisis of confidence. Can anyone tell me if what I'm wanting to do sounds reasonable, and legal!? I'm aware it's perhaps not ideal but I need to work with what I've got now.
As I will be needing the boiler connected and commissioned I'll be paying a plumber to do that anyway but am a bit afraid they won't like the water side of it and say it all needs ripping out and doing another way.
Are there any regulations I need to be looking at for all this too?
Any advice appreciated and if there's any friendly plumbers in the Fife area want to take a look and give me some advice I'd be happy to pay for your time.
