Distress replacement of existing combi boiler, have electric shower rarely use bath, condensor not worth extra expense, only running 5 rads and washing hot water.

Got a quote that trying to work out, heating sytems not being my specialist subject....

- Supply & Install Vokera Excel 25 with 2 year warranty: £1095

From online reviews sounds like bsort of thing install just before selling place, don`t seem to rate highly for reliability?

- Supply & Install Vokera Vision 25c with 7 year warranty: £1375

Is this the same boiler with an extended warranty and Vokera tyring to rescue reputation?

Existing boiler is a Gloworm thats been reliable for 15+ years but provokes teeth sucking from gas fitters.


- Supply & Install Worcester Greenstar 25i with 5 year warranty: £1655

Bosch Worcester seem to be a better choice for reliablity at a cost?

- Supply & Install Vaillant ecoTEC plus 825 with 5 year warranty: £1905

Is Vailliant the Rolls Royce of boilers or will it cut my gas consummption in half or some other reason for big cost jump?

- Heating filter: £100 (Highly recommend as this protects boiler heat exchanger from any debris that would cause damage)

Would have thought there is filtering internal to boiler , seems like an expensive add on?

- Powerflush: £350 (Recommend when you are upgrading boiler but keep existing radiators/pipework)

At this ort of cost replacing the rads would seem cheaper, 350 quid seems like an expensive hosing through, is this really neccessary?

Any advice comments much appreciated.

Thanks!
