Thanks Grasmere.
iwill have aword with the chap and see if ican leave immersion tank in, good point that as being able to switch to electric
when needed is handy.

My plan is get this thing fitted. and then next summer time look round for something that will fit back in its slot that shouid be here (Arga) last owner of the house was mental ripping that out

[lozz]

Well its all in , & what a fookin nightmare, all pipework ripped out,
copper tank gone,

new combi in but no worky, gas fitter as flooded the pcb board, and he fled like a rat on a sinking ship the bastid,

[Bailes1992]

I hope he's offered to pay to replace the board?
By flood I assume you mean he's soaked the bloody thing?
Providing he hasn't powered it up it should be fine once it's dried out!

My Parents have just bought a house as an investment to rent out. We got a plumber in to isolate the gas from the boiler. We ripped it all out ourselves then got the plumber back in for a few days. We put the pipes in and he came round soldering all the joints, fitted the boiler and set it all up for us!

I want to look into how combi boilers work. I.e. if the water intake is already up to 60°c would it still kick in?
I'm thinking when I move out to keep the old copper tank with an immersion heater. Get some second hand solar panels and connect it in parallel straight into the immersion heater without the inverter. Then use the hot/warm water from the tank to feed the boiler. If that makes sense?
Obviously I would have to control it with a thermostat to ensure that the water in the tank doesn't go over 60°c or so.
Then I have the issue of water pressure to look into

[lozz]

Ihavent paid him a Bean so he will have to Return and sort it,
Board is soaked, (f*ked)

Ihad a play with the old boiler before it was ripped out,

They is got sensors in them. Flue/flow and overheat,

So no they wont kick in if there upto temp, you wouid have to by-pass room stat/ and sensors on boiler, (dangerous)


got the old boiler fired up before it got scrapped, it was only a Venturi/preasure switch fault,.
couid of repaired it for 25 notes, ah well its gone now,

Idont mind playing with electric but Gas is a no no for me so im just going to have to wait/freeze somemore & hope this pile of eyetalian crap combi
brand new at that..can be salvaged /repaired.

lesson learn.. = pay peanuts & you gets Monkeys,

Very true!
Fortunately the guy we use is pretty trustworthy. We pay him a day rate plus consumables and supply materials ourselves. He doesn't hang about either!

The boiler in our house in an old Baxi boiler behind the fireplace which was fitted when the house was built around 1960. It doesn't get used between March and October, gets serviced once a year before winter and never misses a beat! Other than a few thermocouples it's never gone wrong! We have electric showers so hot water isn't an issue. We use the kettle to do the washing up! If we want a bath then we can fill the bath using the shower.

I find it quite worrying how unreliable modern boilers can be!

[lozz]

ifound out what the 3 tanks are for in the loft,
they are used for the cold water supply for the Shower's ive left them in,
there supposed to save you from getting scalded if the cold water supply preasure drops, seen it happen with elecy showers
but not c/h fed showers, left them in just incase,

Hmm he didn't mention any sort of temperature sensor which is a bit of a shame. Might have to rethink my idea.

That's a genius idea for the showers!

[lozz]

You can run a system two way so you can keep copper tank,
not sure how it runs off solar power, tho,

But iknows the combi's are full of stat's. so they carnt go over the temp set -on the control on Combi or room stat,

Perhaps you couid just use copper boiler for Bathrooms run off Solar pannel,
once combi is not powerd up theres no supply from it to hot water unless called for, so perhaps a bypass valve wouid be needed,
(just guessing tho)

There is a few good plumbing forums,might be worth a look on there to gather some info,

Them old Baxi Back boilers are reliable but Expensive to run, iwouidnt like your Mars/dads gas bill,
some of the houses that Baxi's where installed in the chimneys where ASBESTOS lined.

[Captain Jack]

Our oil boiler failed for the 2nd time in 3 months. Freezing at the moment and making do with immersion water heater and oil filled radiators for warmth. The boiler is only 7 years old.

It's not too bad!
During the winter it comes on for two hours before we wake up and two hours mid afternoon. That does out hot water for the day and the house is well insulated so it keeps the house fairly warm.
If any of us moan we're cold we just get told to put a bloody jumper on

[steve_earwig]

Keep hold of it! It's like running a 405 XUD, a bit primitive and inefficient but it's all known about and the parts are cheap. If you did replace it with something more modern you'll end up having to replace parts on it and maybe the whole unit after 5 years or so, factor that into your running costs.

The boiler is only 7 years old.

Nothing lasts long these days, the manufacturers have really got a handle on this built-in obsolescence malarkey. When we got married 5 years or so back my dad bought us an all-singing, all-dancing washer-dryer. The old machine was Yugoslavian-built, clunky and didn't do much other than wash. The new one, well, fabulous. A few weeks back it stared flashing up a fault, I Googled it but it said it was a temperature sensor on the dryer side. Can't be that, the fault comes up even on drain. Had the Hotpoint guy come out, 50 quid to change the sensor and the fault cleared. 3 days later it blew the main fuse Cascade failure alert.

We gave the old one to a friend, it's still going strong

[lozz]

got it all fired up.

coz iwas bored/cold ihad the wiring diagram out,

with no room stat being used you needs linky wire,


ive got the preasure on the Guage up to 2bar, is this right or wouid it need more?
anyone know?

thanks

[grasmere59]

2 bar tops as the safety lifts at 3 I think and if that was a cold pressure you have to allow for a bit of a rise for expansion,it should tell you in the handbook.

[lozz]

Cheers grasmere,

iwas just taking a guess at two bar, instruction manual as diaspeard .

its not making any banging noises yet so 2 bar shouid be ok,
if not iwill have to let some out,

This combi seems good, it feels like Benidorm in here at last,

plumber as missed a pipe or two, no hot water in kitchen or main bathroom,

filling bath with hosepipe later is going to be fun,
