However I’m contributing more CO2 to the atmosphere, (As if I care) by not having one of those new fangled condensing boilers (NFCB). Now my old fashioned boiler (Nearly new, due to getting it fitted before the diktat came in from the government, that you had to fit condensing crap), works by heating my water and storing it in an insulated tank. Works for me, as throughout the day I have hot water on tap. (Boiler on for one hour morning and early evening, with half hour top up at midday). (From what I’ve read and heard, most new installations do not have hot water cylinders. Why not?)
If you have a NFCB system that’s fitted now it’s akin to having one of those old fashioned Ascot boilers that just supplied hot water on demand.
Remember them? From turning on the tap it took forever to get a decent temperature hot water.
Well the new condensing boilers as fitted to my son’s and eldest daughter’s houses are modern day clones.
To do the washing up just now in my abode it only took about a fifth of a gallon at the most in order for me to have piping hot water entering my washing up bowl. (I do the washing up, her indoors knows her place and does the ironing)
At my son’s house it takes for ever and at least three gallons before just tepid water issues from the tap. Five minutes later if you need to refill the washing up bowl, you have to go through the whole rigmarole again, FFS.
Did TPTB envisage this when they decided to meddle in things they don’t understand, all in the name of preventing the utter twaddle of man made global warming?
No wonder we have a water shortage if we use at least fifteen times as much water before it is hot enough to usefully use.
Wankers. (In my time as an engineer they were known as “non technical terrorists”)
Aren't the things that dispense with the hot water cylinder "combi boilers"?
ReplyDeleteCondensing boilers can still have a tank.
Funnily enough we have had condensing boilers for the last 21 years, (before most people new they existed) the only reason I replaced the last one was due to it being a floor stander and it was stuffed when our cellar got flooded, could not get new circuit boards for it. The new boiler, now 5 years old is a Keston C40, that modulates its output depending on heating demand. We live in a 6 bedroom (1889) stone build detached in the heart of the Pennines in West Yorkshire. Our gas consumption is 37,000 kWh per year which includes a gas hob, before fitting the Keston it was 40,000 kWh, I think due to the old boiler being on and off not modulating.
ReplyDeleteCondensing boilers (if you select the right one) can be a boon in reducing the gas bill. I don't give a flying fig that they reduce the carbon foot print. THEY SAVE ME MONEY!!!!
As an addition to the above, we are building an extension to the side of the house to replace one thats falling down. I will be putting a mains pressure hot water cylinder (300 liters) with dual heating coils. With the boiler on full throttle it should heat the upper 2/3 of the tank in 10 minutes whilst still returning the heating water to the boiler at less than 55C so by ensuring it is in condensing mode at all times. I just love the fact that you can get so much additional heat by making sure the boiler condenses all the time and you get the "free" heat from latent heat in the exhaust gas.

Hi, the solution is to get a combisave valve fitted...
