Would appreciate some general advice on the following please.

Our system comprises of a glow-worm boiler and a tornado stainless 170 litre unvented tank upstairs in the airing cupboard. On the top of this is a little red expansion vessel with a gauge on it. There is nothing in the loft. Is this a condensing system?

Anyway, the bottom of the tank has seemingly corroded and we have a water leak into the downstairs below. The gauge on the red vessel is still at one bar. The water around the bottom of the tank is substantial and its fairly obvious its the tank that has failed.

This is obviously bad news and just weighing up some options. The system was installed in 2005 when the house was built. It has 2 valves. a pump and an immersion heater.

A few questions

1, Straight swap of the tank is the easiest option but is it the best option or should i take the chance to swap the lot to combi? What is the likely cost to replace this tank and what is the rough cost to go combi? House is standard 3 bed semi in S.Yorkshire

2, Do i need 170 litre capacity and if not what is a smaller tank likely to reduce the cost by?

3, Best way of going about getting the right people to do this job? Google, checkatrade? What should i look out for? questions to ask?

4, What kind of warranty will i get with any work done?

Thanks for looking.

Ok the red vessel is for the heating system and is an expansion vessel.
Personally I would never advise customers to swap over to a Combi unless space is premium and you know the pros and cons.
To fit the tank you need to have the correct qualification for unvented cylinders.
size wise is dependant of how many baths/showers you have.
 
Ok so keeping the system looks best (not a fan of combi's myself to be honest). Is the qualification for unvented cyclinders common, obviously when i speak to someone about it they will tell me if they have it or not.

The property has one bath and one water fed shower in a seperate en-suite. Am i better of keeping the 170 litre tank?

Any idea of rough cost to replace this tank?

tbh the price difference between 150ltr and 170 is minimal.
Yes qualification is common and honestly check before you employ someone to do this as consequences are huge if installed incorrect.

£800 ish.+ vat

Thanks quilts i would make sure to check for qualification. The current tank is a telford although google tells me several brands are available, any to stay away from in particular?

Is it worth replacing the 15 year old pump at the same time?

Is that £800 including Labour?

pump?

I presume you mean the central heating pump. If so then yes.
Re the tank yes I would be looking to charge that. Telford are fine.
 
Just a thought i have had overnight. The just replaceing the tank seems the cheapest and best solution but is there an argument to be had that because the boiler is 15/16 year old i could end up replacing that aswell soon? It is a glowworm boiler but im unsure how good/long they generally last.

indeed I would budget for that to be replaced as 15/16 years is good for a boiler now.
 
so new boiler and new unvented tank...........likely cost including labour?

vs the cost of converting to combi boiler?

although i acknowledge that im not a fan of combi boilers either and im guessing the fact i have a bath and water fed shower will mean a decent size combi would be needed to get a good flow rate?

Boiler is dependant on many things in the system design, controls, condense waste, flue termination, wiring back at the boiler, gas pipe size. Very hard to give a solid figure but work on 2k and this will give you a very good budget with a top A rated boiler.

Location is also a factor as labour costs will be different on area London - Liverpool for example.
