Central Heater Boiler replacement


Terry Brown
Resolved

Likes # 0

My boiler is now 17 years old and while it is doing well, it will not last forever so I am looking for a new boiler.

If you had had a combi boiler fitted recently (last 2 years) could you give me the name & model of the boiler and satisfaction level from 1(poor) to 10 (Very Good)

Noise , efficienty , gas usuge (compare to previous boiler), servicing required and number of radiators (mine is 7)

Thank you

Terry

I, having been a building maintanace manager most of my working life prefer the traditional boiler feeding a storage cylinder. The efficiency can be high with suitable controls and insulation. Also combi boilers will scale up in hard water areas

Thank s for the thought, however with our lifestyle we do not use water at regular times each day, and so to keep a tank of water hot 'in case' seems like a waste.

Correct me if I am wrong in thinking this way.

Noted Terry. I live in a very hard water area and judging how often we have to descale our kettle I would not consider a combination boiler.

We also live in a hard water area, however the people who we have (almost chosen) are putting in a chemical descaler (in the water) and installing a Magnaclean device which attracts and holds any residue (sludge)and needs to be emptied annually (like the ubend of a sink pipe),and that will be done for the first 7 years as part of the installation price, after that it is (currently) £67 (at todays prices) per time.

Thanks for your feedback

Are you getting confused between a combination boiler and a condensing boiler.In a combination boiler, the water heated in the boiler heat exchanger comes out of the taps, a condensing boiler heats the water in the boiler heat exchanger and feeds it to a primary coil in a storage cylinder heating the secondary side tap water by conduction. The flue gases in a condensing boiler are at a lower temperature than a conventional boiler and can be such that the water vapour generated in the combustion process condenses out into a drain pipe. It is possible to get a condensing combination boiler with the obvious benefits. With which ever type of boiler you choose a chemical descaler is not necessary. Chemical Descalers are used to remove lime scale deposits as used in kettles. Water treatments are used to prevent iron deposits in the primary system on large commercial systems but I have never used it on a domestic installation.

I hope not.

I think you'll find that what they are actually going to do is add a corrosion inhibitor to the sealed heating circuit. That's the water that is pumped through the boiler's heat exchanger, the radiators and associated pipework. In an ideal world the system should be drained and flushed once a year, and the corrosion inhibitor renewed.

That was the point of my post. To avoid any confusion. There is a difference between a descaler and a corrosion inhibiiter. A corrosion inhibitor in my professional opinion does not need to be replaced annually but only when the system is drained down for maintanance etc. It should be topped up of the system develops a leak. My conventional oil fired central heating system had not been drained down for some 13 years until last summer when I carried out some alterations. A very small amount of black sludge had collected at the drain point being the lowest part of the system but the majority of the water was almost clear. Most of my radiators are cast iron and the system has never had any corrosion inhibitor installed. Contractors will always recommend things to the un initiated after all it means more profit. If you want peace of mind use a corrosion inhibitor but generally in a domestic installation it is not really necessary. The main point with a domestic central heating system is to have the boiler regularly serviced by a competant person to ensure correct combustion.

My daughter is thinking about renewing her back boiler system for a Combi Boiler. And looking for reviews for most boilers would put you off buying one.

Like computers probably it is only the ones that have problems that post most.

We do know the local plumber that most of the family use,So will probably go with his advice.

But a bit of a minefield out there if you are not sure what you are looking for.

buteman. If you can find a local plumber who has gained a reputation for good work I would suggest you seek his advice. I recently had difficulty finding a good reliable jobbing builder, now found one, He has just started up on his own. "One man and his dog" with a good student as a laborer out of term time. He has gained a good reputation in my area having carried out various jobs. He made an excellent job of replacing an asbestos sheet roof on my garage with a flat felt roof and replacing a couple of chimney pots that were looking dangerous.

Yes he is good and his prices are always below average.

He has already installed Combi boilers for a few of the family + hot water tank and central heating pump for myself.

He also prioritises his call outs and will attend pensioners and people with health problems first to make sure they are not without heating if they have problems in the cold weather.

The problem with good tradesmen like that is they get very popular as folk recommend him to others and eventually he may not be there when you need him.

But so far so good, when you get a good tradesman you stick with him as long as possible.

My Daughter stays in a 5 bedroom 3 storey house so I would imagine that she would need a bigger or better boiler than the others in the family so just a matter of getting him in for a quote.

Just out of interest where would they install it.

Kitchen which is on the bottom floor.Also a small bathroom on the bottom floor which would be best I suppose.

2nd floor bathroom and bedrooms.

3rd floor bedrooms.

Cant go in the loft as it is the roof is almost flat with only room to crawl.

brother in Law has his in the kitchen which was just a replacement.

Other 2 in-laws have there's in the attic so not sure where the ideal place would be.
