18" is a very poor static head so you have correctly identified your sister in laws problem. Lifting the tank to it's highest posible position (3ft) will improve things. Another thing you can do is increase the cold feed from the tank to the cylinder to 28mm leaving off all valves (this does...

There is a process called tosh nailing which only the most skillful of joiners know how to do. However, if you want to attach a piece of timber to a plasterboard wall then screw the radiator brackets to that then this is the method to choose (perhaps some no nails on the back of the timber...

It's the old turn down your boiler thermostat and save money advice that the government regularly puts out. However, the government are not heating engineers. If you have a modern system with all the latest controls fitted and your home is heavily insulated then you need to run your boiler...

[/url] The only snag with them is that they're so bulky and you often just don't have the space to get them in. I've also come across this (16mm?) copper on a few occasions (it would be interesting to find out who manufactured it) On the few occasions I used a 15mm drift (socket forming...

[ I was pondering on the one pipe system as i will be adding antifreeze to it for when the property is left alone.....Its good to know that the one pipe system works......as far as getting the fittings that is no problem in Romania (they are not as modern as us) Lots of good old second...

Sounds like you're using the old one pipe system. A good old fashioned way of doing it and you can use the allowed (1/10th of circulating height) dipped return to connect the return at floor level up to the boiler. The Expansion/feed tank will need to be (at least 1m) above the heating flow...

Another point that I'd like to make on this is how the thinking on retirement has changed over the last 40 -50 years. Back in the day it was thought that when a person reaches 60+ he is then well passed his best and it would make economic sense to retire that person therefore letting someone...

It's possible, but things have now moved on from the days when gravity ch heating was installed. Things you will need - 22mm pipes all round - yes no problem. x3 3/4" tapped out radiators - very hard to get hold of these days. x6 3/4" - radiator valves - again very hard to find...

Unity brothers ! Both public and private sector workers need to stay together on this.

We are all living longer so we all have to work longer is the current governments message to us all, right! A life insurance statistic also says that "if we retire early we live longer"! Lets turn this around so it must also mean that "if we retire later we die younger"! This government...

It could be leaking from the gland nut at the top of the valve. If it is just give it a little tweak with your grips. If not, (as above) just fit two completely new valves (they're cheap enough these days) to cure what I would describe as a niggle. Servotech,

If you're poor as I am! :cry: before you add anything else give this a go - Empty the radiator in the usual way but instead of adding fernox just add a cup of washing up liquid. It's an instant cure for boiler kettling noise (if that's what the problem is). Good luck (cheapskate :) )...

ASHP/GSHP (simply explained) I'm often asked is there enough heat in the ground or air to directly supply all mt heating and hot water needs? The answer to the question is NO. The ASHP/GSHP system needs a trick to do this, which is to use the refridgerent cycle to perform this trick. What is...

A very popular leak is when the bath taps are being run a proportion of water runs down the taps stem then through the seal between the tap and the bath then onto the floor beneath and eventually making it's way through the ceiling into the room below. Granted a little odd that the leak is...

This is correct, although you can balance a loop on a one pipe. What problem are you experiencing that makes you think balancing is the answer? Servotech,

And from 2016 all new builds will have to come with energy supplied from a renewable source. So even if you wanted a gas boiler etc fitted in your new home, it will by then have become illegal to do so!! Servotech,

All this ASHP/ GSHP is - is really just recycling the old refridgerent technolodgy again (which was kicked into touch a long before my time)! Only this time the government under the green banner has fell for it hook line and sinker (at a huge cost to the tax paying public) ! Servotech,

I'm afraid this is what it's like today with all taps - we are now in a throw away society. At one time, not that long ago all taps had standard washers and a packing gland (no 0 rings) which you could repair until the cows came home :D Not so today :( Servotech,

Nothing derogatory about being a plumber. I am a technical grade plumber (which is the highest that you can ever be in plumbing). Our ASHP are all fitted with expert trade knowledge and are all of the finest/modern designed systems that are around today. If you wanted to get technical about...

Cutting through all that technical COP talk and moving onto the practical realalities -: An ASHP customer on Friday told me that the bill for the last quarter for heating her small bungalow via a ASHP was over £400!! I know it's down to how much money you earn or that you've got, but that's...
