New boiler

[RogerS]

The room stat I linked too learns the heating curve of the room too. If, for example, you set it to make your bedroom 18degC at 9:30pm over the course of a few days it'll learn that it needs to start heating the room at about 8:30 say if the temperature is currently 15degC.

I designed and build one of those - microprocessor based - about 30+ years ago [/smug git mode]. Pity Dragons' Den wasn't around then...or that I had the faintest idea about sales and marketing.

So............... Assuming you've got a partner Roger, has it stopped them constantly turning the thermostat up / down?

I recon I could just about get away with it by saying the stat must be bust (she isn't technically minded) :wink: Wouldn't half save me some frustration ](*,) - unless she found out (hammer)

Yup

Love it :lol: It'sw on my "secret" to do list :wink:

 

[RogerS]

There is a much easier way, Bob. Just give her a control...tell her it's a wireless one...only it isn't..nor connected... :twisted:

Actually it's too late - I'm stuffed :shock:

I was making a coffee and left my last post on screen - you guessed :!: - she read it - - now wants to know what the rest of the "secret" list is :roll:

Luckily her memory is cr** so hopefully in a week or two.....................

cheers Bob

Not sure what your current thinking is, dw, but a couple of other points re combi spring to mind. Not sure if they have been mentioned.

1) Have you got sufficient water flow from your mains. Not the same thing as pressure.

2) When your combi stops working so does all your hot water as you won't have an immersion heater unless.....

3) with some combis eg warmflow you can retrofit them into an existing system and still keep your hot water cylinder etc. Just that the rads are unpressured. I considered this when I put in the new boiler so that i could feed the downstairs hot water (kitchen and utiiity) from the combi directly as these pipes were furthest from the hot water cylinder. In the end I went for a secondary return and in hindsight I should have paid the extra and gone for the combi hybrid.

Havent got any quotes in yet.

Turned the threeway valve by hand yesterday to get the radiators on stream and that took some leverage on the axle to turn. (Honeywell motor works but not enough puff to turn the valve)
Must be corroded up.
assuming that a new system I would have to wait some months before done should I refresh the system water with some Fernox or something?

If it's not already been mentioned, and you do decide to install a room stat... Consider a programmable one. We have one that allows us to program the temp for 6 time periods for each day of the week.

(Oh, and we've used it with both normal valves and subsequently TRVs. The latter allows us to refine the temp at room level and works very well).

Wot 'e said DW, in fact I doubt that you could run a condensing boiler without a room stat.

I do. If you have rad stats, I can't see what purpose they serve.

A vital one - it stops the boiler cycling. Once the rad stats are closed because the room temperatures are up to the desired setting, hot water returns to the boiler without passing through the rads and the boiler switches off. If the rooms stay up to temperature, the water in the boiler will cool until the boiler turns on again and cycles water through the system until it gets back to the boiler and turns it off again.

We replaced an old oil fired boiler about 3 years ago with a Worcester Bosch oil fired condensing boiler. At the same time we divided the radiator circuits so that the upstairs and downstairs are on separate circuits, each with a separate time controller and room stat. So, in winter the downstairs comes on at about 5pm but upstairs only comes on at about 10pm. The bedrooms are also set to a lower temperature. We also added an additional 6ins of loft insulation to the existing 4 inches.

Overall result has been to halve our oil consumption - which effectively means that we are spending no more on heating than we were 5 years ago.

10" of loft insulation would never work for us because we use our loft for storage changing contents summer and winter etc.

Not a problem DW. Originally we had loose boarding across the 6" joists with 4" of insulation underneath. Obviously increasing the insulation to 10" raised the level to 4" above the joists, so I had to lift the boarding, add additional joists across the existing ones and lay the additional insulation between the new joists. Then I just boarded over the new joists. Our loft is very full, so I did one end at a time and just moved stuff from one end to the other as needed. Cost in our 4 bed house was £200 for additional insulation and £200 for additional 6" joists and boarding. Paid for itself in no time.

Not only has it cut our fuel costs, but it's made the bedrooms far more temperature stable. As I understand it you live in a bungalow? I would have thought that added insulation would make the benefits even more desirable in a bungalow.

Roger your setup sound great.

My loft has a 200sq.ft model railway installed and could not cope with the changes you have made. Although the railway is now only a scenic attraction to me, it was a 7 year portion of my life. I was able to provide the time because of my selfemployed timing arrangements, (I had a local agency and made my own appointments)

Ahh! Form before function. Point taken. :mrgreen: =D>

Now you've done it, dw. You've let the cat out of the bag and there's going to be a never-ending stream of visitors :wink:

While reading up on MagnaClean I came across this in their FAQs.


MagnaClean Professional has been designed to last for the lifetime of the boiler, normally ten years.

Ten years for a boiler? :shock: :shock:

 

[Digit]

If that Rog. Most can be serviced longer than that if you can get the parts, ie circuit boards. In hard water areas combis can fur well within that time if not fed by a softener.
Our boiler uses many standard parts but the PC boards could well be non stock PDQ.

Considering the widget is about £80 - should pay for itself quickly. Go for teh Twintech one - it's around £100 but catches non ferous stuff as well.

10 years seems to be the "buzz" figure at the minute and there's a school of thought that technology moves on enough in that time to make the environmental benefits worth forcing consumers to change (whatever the cost).

My last Worcester oil boiler was 22 years old and still working when I took the opportunity to buy a new one just prior to the legislation coming into force.

Because of that, I bought a £1700 Worcester Bosch for £700. High efficiency but non condensing and within the law as it was prior legislation. I fitted myself and had it commisioned.

I did the efficiency comparisons and the sums and concluded that savings would take nearly 15 years to recoup and my boiler would probably last longer than a condensing model.

No brainer really. :roll:

Gave my old boilers' guts to a neighbour and his is still going without using the parts. must be less efficient but his attitude is that he would be gone to his maker long before he could get his £2 - 3 grand back in savings

Sounds normal Lons, if you haven't got the latest digital toothbrush the world is passing you by!
