Does anyone know how to reset the service engineer lights ("SE" code) on a a greenstar 30CDI? Was wondering if it was a key sequence or a laptop...
You're damn right i'm not a heating "installer". I regard the average "installer" (and stick yourself into that bracket) as a plank who has little...
my bill was not an estimate. that was meter reading. the previous owners bill was based on meter readings as well (my meter is outside)....
boss white and hemp would be my choice. loctite 55 is not bad but not as good as boss white and hemp. In my humble non plumber opinion.
mmm.. I appreciate in commerical plumbing that threaded pipe is used. But in domestic all i've seen is compression joints. The Viessmann boiler...
Sorry I should have made myself clearer. The jig that comes with the vitodens 300 WB3B (to be specific) comes with a jig that will only take...
in no particular order or preference, but it does a lot more than this: Reduced room temperature mode. Heating slope alteration, changing the...
okay thanks guys, i think i'll get the rubi. just the videos of the husqvarna look quite impressive. Having said that i'm not a tiler! sanj
Has anyone tried any of these machines? I have bought some porcelain tiles that are about 10mm thick and my electric tile cutter just isn't up to...
I still stand by everything I said. I got fed up of people not bothering to listen so i gave up. Heating engineers shouldn't even be allowed to...
I would just like to clarify one thing. When I said I save 4% gas over non-weather comp. This isn't a strict like for like comparison as the...
I'd agree with what billy bob says. My Parents have a Worcester 30CDi, its not bad. 1. the WB jig is not good if you have top flow and...
The diagram hasn't neglected anything. If you install to DIN 1988 you don't need the T&P valve. That diagram shows DIN 1988 hence no T&P I...
From the diagram it looks as though its a PSV. Spring loaded to relieve at a pressure. Nothing to do with temperature. My mum and dad's santon...
when i lived in germany, my system did not have a temp valve. It was totally reliant on pressure. Most of europe does not have the 2 port...
If you buy a system that is to a DIN standard, I believe its DIN 1988. Then these systems only come with a Pressure Relieve Valve, not a...
few boilers actually have 28mm connections, therefore the only benefit you have from having such large bore pipe is reduced frictional losses....
to cause an explosion like that in the picture on the bbc site, you must need a hell of a lot of gas and air for that matter.
I said bernoulli's equation does not apply to compressible flow. Yes there is an equation for it which you looked up in your book. However you...
The reason for the difference is one of a number of factors but its primarily to do with flow velocity and density. The equivalent lengths change...
