PoS thermal store

Used on all the new builds round here.

Just bants though isnt it. There can be intellect in making witty insults (even if that brings ones wife into the occasion). On the other hand taking it personally shows you have never worked on site and if you have they clearly weren't worth working on.

Ive been as bad as benard greengrass and screen shotted that quote :lol:

Like I said. Didnt think you would complain ;) Bernard greengrass may of though.

Unless Steel complained about what you said. I cant see him doing. Was it not just a bit of bants?

The boiler is one of the main boilers for house bashers. Its a relatively big combi being 35kw. Its been set up with upstairs down stairs heating. No need to see under the boiler ;) An unvented cylinder could be in there. The issues you would have are. Need to find the hot and cold services...

Crosswater valve?

It stands on its own :)

Lower hear values with regard to flow temp 70/50 compared to 50/30

@Steelmasons Theres a gas appliance that has an input of 11kw and an output of 17.5kw ;)

I know how they do the 109% but 120% o_O

All new cars cant have r134a. Old cars still can but as of last year car manufacturers had to move away from it.

Checked every year. Although you'll need someone who has their fgas

Or you could do the job in copper and make it look worse than if it was installed in plastic.

Typical 600 x 600 single panel would be approx 600w with a Dt20 n 15mm that would be approimatley 0.05m/s through that size pipework. A tad low one might say. With less that 0.001 m head resistance per m I reckon my rad would be ok on 50m of pipework and a high resistance hex ;)

Wasnt being bashful. Your reply of "yeah okay" started this. Would always look to design a system around 1m/s velocity with a max of 1.5m/s minimum 0.5m/s (although my example showed 15mm would be well oversized for this). Pipe size would depend on kw required, length of pipe number of bends...

Lets not be shy @terrydoh . If we had a typical 600 x 600 type 11/k1 with a flow and return dt20 pipe in 15mm would we have an issue?

Im not sure about how velocity being too slow on a sealed system is detrimental.

Looks like mlcp debur shavings
