    Buffer Tanks - 2 or 4 port connections

    the gas boilers will kick in either if the biomass goes into fault or when the biomass is running at full power and the return temperature drops below 65 degrees.

    Buffer Tanks - 2 or 4 port connections

    exactly, we need to redo all the calculations to check everything will work, the hydraulics are ok. dont think we'll put another boiler in but will get the council to accept that a 200kw boiler is not gonna cover 70% of a 1.4mw of peak demand. although the biomass will be running flat out and...

    Buffer Tanks - 2 or 4 port connections

    had an email today from Wilmot Dixons QS basically saying to give them a list of what our demands are to take the installation on and give them a price for it. They are getting desperate as the council want to take ownership of the system to claim RHI but WD cant fulfil their contract without...

    Stupid jokes

    Paddy and Mick are walking down the road when a prostitute walks upto paddy and says "do you want to go to bed with me for 40 quid" Paddy replied "well i'm not really tired but could do with the money!"

    Buffer Tanks - 2 or 4 port connections

    Possibly, but I think now the system has been commissioned, the council will not accept any AI's or variation orders for major system and plant alterations. WD will lose out big time.

    Buffer Tanks - 2 or 4 port connections

    The original tender design was done by consultants in London and a spec produced for pricing. Wilmot Dixon won the contract on that spec. When the contract was signed, the consultants pulled the design and said WD had to use their own design to which they just rebadged the original with out...

    Buffer Tanks - 2 or 4 port connections

    They were in the spec that Wilmot Dixon sent us as part of the tender docs. We gave them 3 options, we put in a ridiculously high price to cover all the penalty fines we would get for not providing enough heat via biomass, or we knock the energy centre down, and build a new one with a suitably...

    Buffer Tanks - 2 or 4 port connections

    It was an absolute joke. The peak heat load worked out they say at nearly 1.6mw, and part of the agreement is that the biomass boiler covers 70% of that. No chance!!!!. Then they reckon the heat loss over the whole system being in mind there is 230 hiu's, all pipework above and below ground is...

    Buffer Tanks - 2 or 4 port connections

    im going to look at a new install district heating system to 3 blocks of flats with 249 flats each with its own HIU, 8kw heating, 37Kw hot water. The plant room has a 201kw herz pellet boiler and 10000 litres of buffer as the lead boiler and then 3x 530kw gas boilers as backup. we are tendering...

    Sizing rads for ground source

    has the system been designed or is it a case of using the existing system and changing rads? if you have the heat loss calcs for each room then you shouldnt need to oversize the rads, just put in what is the required output for that room.

    Sizing rads for ground source

    you cant mix and match your DT!! and a DT of 50 degrees seems a bit drastic, 70/20 split?

    What a way to start the day..

    well Lucy is the goalkeeper so saving 2 of the 3 penalties made her the hero of the team. Some parents can go way over the top, my mrs spends the half hour shouting and cheering the kids at top voice and the kids love it, and the other parents just stand there laughing. but she has a passion for...

    Pre insulated underground pipe?

    underground pipe is not very flexible at all, and as Nostrum says, you have special fittings to convert to copper etc and usually a specialised crimper is used. On the Rehau you can use preformed elbows to get you nice and neatly up the wall but again they are expensive and bulky once you fit...

    What a way to start the day..

    was in exactly the same situation this morning, freezing cold, snow blowing accross the pitch, me playing ballboy to my daughters under 10's cup match just to keep warm. Oh what joy!!! but they got through to the final winning 2-1 on penalties after 0-0 extra time. so makes it all worth while:50:

    Pre insulated underground pipe?

    uponor is ok for short runs but if your looking at longer runs or minimal heatloss then look at Rehau Rauthermex. its expensive but well worth the effort. REHAU RAUTHERMEX pre-insulated heat transfer pipe, there are others like Calpex, and Brugg which basically use each others products but Rehau...
