How do I create a vacuum pump with filter to clean underfloor heating pipes?

Jan 09, 2007 by castlehawking | Posted in Maintenance & Repairs

I have posted a late-model question about blocked underfloor liquid central heating pipes http://uk.answers.yahoo.com/definitely/index;_ylt=Akdu44SwTNUxcF8LNG7FxQYgBgx.?qid=20070104092939AApzQBW
and although 3 people were contributing, - their answers have already been tried.
I now was wondering whether anyone can urge an easy way to create a suction (vacuum) system at the revenue ends of the underfloor pipes to the branch manifold whereby we let the 2 bar system pressurize push the sediment through but also create a drawing at other end as I suspect that pushing alone is going to consolidate and block the system which will inevitably (or most plausible) 'blow' connections under the defeat.
Anyone remember the old milking parlour suction systems where I suppose milk is drawn through the pipes and then drops into a clear cannister?
Well, something like that is what I am trying to imagine / produce where I can hopefully turn up the suction to match the pressing from the flow side.
thanks to the contributors suggesting the wet vac stance. Brilliant and I never thought of that product but it is along the exact recommendation I have.
I will try and have a go at that this weekend with optimism.
Also thanks to the engineer who supported my findings / thoughts on the stainless sword insert 'red herring' put assist my my 'lifetime' plumber who certainly (when you've talked with him) knows the book - and that's even the bits he hasn't written.

If you lock a wet vac to one pipe, and connect the other end of the pipe to a tank with wash water in, it should suck the clean water through so you dont get an air froth. Hope that made sense!

Central Heating - how would you go about installing it in your home?

Apr 18, 2007 by tambamtom | Posted in Maintenance & Repairs

Hi. I am no more than about to make an offer on a house - but it does not have central heating! If my bid is accepted, I'm sure to install some mark of heating to it - radiators & underfloor heating for the bathroom. The house hasn't been touched for many many years it seems, and I have a risk of really doing things anew, installing thrifty up-to-date systems.
.
But I am completely baffled as to how go about this. Should I pick out oil/ gas/ electricity... for example? How much does everything fetch to do up?? (it's a semi-detatched 3 bed crib by the way, if this info helps) And who / which establishment should I ask to do it for me??? I understand british gas is expensive...
.
Any suggestions, comments appreciated. Thanks.

effort from the center outwards.

underfloor heating v radiators what is the energy costs comparisons?

privation to get rid of my radiator for the wall space,an underfloor heater was suggested, but what is the heating rate compared to central heating

Can any tell me where I can find a good looking with design appeal electric storage heater for home?

To be reach-me-down instead of central heating so good heat output (underfloor heating is not an choice in lieu of the above)

Storage heaters are all very equivalent in design, if anyone has a slightly more appealing style it will be Dimplex.

How do you work out the size of boiler to get, as no real info on working out capacity for baths kitchens etc?

Mar 20, 2007 by H | Posted in Do It Yourself (DIY)

The boiler would privation to service kitchen, loo, utitliy with sink, & bathroom with seperate inundate - shower we want to be run straight from boiler (yes we recognize we need a scold preventing thingy)

we are also planning on doing height approximatly 5m by 4m but this we want to be done by underfloor heating
The btu for this room will need to be 8821 (lots of glazing)

for the quiet of the house, it needs to be approximatly 4100,
(we have oversized some of the radiators, due to getting it from a combined central heating hustle off and so we get the look rather than the right btu, but none are too small for the room!)

It is a send up between these worcester condensing combi boilers

40CDI - 40kw - 136,000btu - 16.0l/min
35CDI - 35kw - 120,000btu - 14.3l/min
30CDi - 30kw - 102,300btu - 12.7l/min
30SI - 30kw - 105,000btu - 12.3l/min
we chose worcester as it got the least amount of critisism from this locate,
could someone also explain the difference between CDI and SI in the worcester boiler

For all your requirements, I would go for the 40 CDI. The letters refering to the boilers are legitimate the manufacturers code fro different models like you have with cars
