They're only about £4.

Hi I think they work the same, if pressure on one end is more than the preset limit on the valve it opens to form a connection? I've been playing with the pump, running it on the third triangle on the auto side. Although I might run them on setting two. I have a room stat also, the...

I've no real problem as such just questions. I've a heating circuit fed off a ESBE mixer valve, flow and return back to the boiler, TRV's on all radiators, All TRV's connected to the flow. Pump for the circuit is a Grundfos alpha2. As I've got TRV's on every radiator I've fitted a...

Hi John In a similar vein, is there a list of items that you don't need to contact the DNO to use?

I think if it was a common problem/issue then they would have, however given how rare it is I guess its not even an issue.

Thanks for that. I've been told 4 - 4.5days. How do you price per day etc?

Hi all. Can anyone advise me what I should expect to pay for ground works/building to get my garage out of the ground. Assuming 450x500 strip foundations, 6x7m garage, 280 brick(total)(3 course) high dwarf wall. All access is easy(next to road), site is level already. I'm in the SW...

If he wasn't running a business the people around him wouldn't have complained.

He was running a business from a domestic property.

Rubbish.

Will do. All the gear arrived today. managed to get a 300kg boiler through the house into its new resting place. Silo is built, just a few bits to bolt onto it, wire the external weather sensor and room thermostats back to it. I'll put some pics up when the rooms 'tidy' so you can see...

I think its always worth checking valves. I looked at a push-fit 22mm iso valve, the actual hole through the middle was 7.8mm!!

As a thread update, I've plumbed the house and 'boiler room' ready for its arrival. It arrived in the country last week, gets delivered to me on Friday, commissioning on the 17th. Can't wait as its getting nippy now with the bathroom at 8Deg!

3m is within permitted development rules, however its distance to next door might be an issue.

Hi Terry 35kw biomass boiler. Heating circuits are done off blending valves. Controls are all built into the boiler http://www.rainbowheatandpower.co.uk/products/effecta-komplett-iii-wood-pellet-biomass-boilers the planned t is feeding 3 radiators, combined 14,000 btu. Regards

Im currently hanging radiators and plumbing for heat. The boiler uses mixer valves with a flow and return. Of what we could call the 'primary' flow and return circuit I need to run a T, I'm doing this in 22mm also before dropping the last 2m to 15mm. Whats the max length off the...

your family room is the size of a new build 3 bed semi :lol:

oops. Good details, further links here... http://www.rainbowheatandpower.co.uk/products/effecta-komplett-iii-wood-pellet-biomass-boilers

If you look at the link you'll see its got a 187ltr integral buffer, 'back end' protection built in. It domestic designed from the off, its designed to cycle also too. Not totally conventional for biomass but very well regarded, very reliable, very efficient. All the protection valves are...

I'm not 100% sure as its a new way of working to me. all the diagrams for their range of boilers that have integral/supplied mixing valves etc have 4 points on them. I'm guessing its something like this... http://www.esbe.eu/gb/en/products/controller-units/vrb140-cra110 I'm going...
