Plate type heat exchangers will probably have a higher temperature differential which will give better heat transfer in a smaller package but they have no ability to store heat or buffer uncontrolled heat sources like WB's.

I'll give Albion a call see if they have a better idea of things. I'm guessing that one of these tanks that have indirect hot water/mains pressure would work better as they have a larger coil inside for rapid heat transfer ?? Trying to avoid any sort of bespoke/special tank as the cost seems to...

Hello I'll be using the water stored in the tank to circulate into the WB. I will use the coil in the tank to get heat out. This way I can have the cylinder vented and have rust inhibitor in there along with it's own metal loft tank. Whether the tank will be big enough or the coil will be of...

I've been slowly rebuilding my heating system for a few months with trv's and rerouting pipes etc. I found that my existing CH pump wasn't upto the job of pumping around all the extra underfloor heating sections so fitted an extra one with a mixing valve. My next job is to fit the tank for the...

I was hoping not to have to use the oil burner very much at all and with the proven unreliabilty of my Rayburn it'd be nice to be able to heat the whole house and get some hot water if it packs in suddenly. A fully integrated system would be complex as I looked into all but this way with 2...

Coil would be nearer the bottom as per standard cylinder or I was contemplating a dual coil which don't cost much more which would shift the main coil up to leave room for the lower coil which is usually for solar. With the UFH pump working on the gravity pipes and the tank contents maybe the...

The woodburner was installed in the house and it's Hunter with 29000btu boiler. As far as integration goes I was going to use a 210 litre albion with a single coil but use the coil for getting heat out rather than putting in then simply connect it up with a pair of 22mm to the existing flow...

I'm contemplating a new water pipe from the road to the house.It's not leaking so it's low on the list but it is old and lead and almost certainly fured up to the max resulting in very poor flow and pressure. I complained to the water company and they installed a new valve in the road and a...

You mean actually inside the fire box where the wood goes? On mine which is an old Hunter most of the housing is the boiler back and sides and it's completely covered with fire bricks no signs of corrosion at all

Don't get me going I'll be having sensors fitted to the tank rigged up to the house alarm in case I fall asleep in front of the fire :lol: That looks like a nice job there did you use DIN rails and what components did you use? I found what looks like a suitable relay 230v 8 Pin Ac...

I'll consider anything that makes good sense with safety paramount I need to figure how to activate the main CH pump and valve without firing the oil boiler using a tank stat it would be the best way of removing heat

I have an old but good galvanised tank which I could use for the FE and it would be easy to fit. I could then use inhibitor without risk of contaminating the other system-thats 2 problems gone :D

I think for some reason that the large kitchen rad worked when the heating was on but like I say that circuit was removed by mistake when I had the pipes re arranged. It either worked by convection or it was getting flow from the bypass valve outlet. Not sure it would flow very well as both...

I was using the same tune by ear method :lol: If it was set too low the rads didn't work so I ended up on about 4 The original heat dump on the system was unwittingly removed(not by me) and I can't rember exactly how it was plumbed but I think it had the flow on the valve 22mm outlet pipe...

I have a Honeywell Bypass Valve DU145 Need some info from the experts about how to set it up on a S plan. Is it supposed to be totally closed when both CH and HW valves are open and then only bypass when both the valves are closed or is it supposed to bypass a little even when both...

Just spoke to a friend who has a solid fuel burner that does his rads and hot water. He uses the hot water from the tank so it has indirect heating via a single coil which quite happily convects to the tank he then has a pump tee'd off the convection loop to the rads which is basically what I...

I had a heating engineer in to move the existing cylinder 3 feet to the right. First he connected the flow and return the wrong way then he forgot to plumb in the kitchen radiator which was also the heat dump for the rayburn so it had to be hastily attached to the normal circuit. During the...

Unfortunately the loft tank is plastic bought new this year 70 gall I think also the pipes for vent and feed are JG speedfit PEX but the last 3 metres to the tank will be copper will this be a problem? Only way I could pressurise the UFH side is by using either another coil in the tank but I'd...

Hello I don't have a scanner or software sorry. The tank would just be a large capacity 250 litre tank with one coil which I guess is acting as a heat store- cold feed from the WB at the bottom and hot feed at the top. UFH circuit would just tap off from these pipes. Single coil in the tank...

Wouldn't know how to post a sketch :? I'll condense it Basically Woodburner>Heat store tank UFH feeds from the pipes (using the same water not a coil in the tank) maybe creating better flow through the WB? Pipe stat on the flow triggers the pump at say 35degrees for the UFH Excess heat...
