Vented versus Unvented

[hwangeruk]

For my new boiler installer, I was going to do the boring "normal" unvented Combi thing.

But reading this webpage, implies I'd be a mug not to go vented:

What do you chaps make of that?

Yes, I would go along with that. A vented heat bank, using a plate heat exchanger, or a thermal store using an internal coil. The heat bank is best.

I'd say go for an unvented system - mains pressure hot water is always nice If you have a bath, and use it, or have a larger house it's best to have an unvented cylinder and a boiler rather than a combi, as even modern combi's take ages to fill baths. If you're a bit tight for space look at gettinga system store, which is the best of both worlds IMHO. Here's Gloworm's one http://www.glow-worm.co.uk/products/ultrapower_sxi.asp

I think you lost the plot. A thermal store gives mains pressure and a heat bank up to 10 bar too.

Combis are not the point although there some 3 bathroom models around.

That's the trouble with this game, so much terminology, its confusing for consumers. Or... idiots like me obviously.

When I say "combi thing", I meant like a normal combi boiler, like my Vaillant Ecomax jobby in the loft.

I need to get a new boiler system for 1 that is condemned at my Ex's house.
British Gas and a remote bloke have quoted for a Worcester Bosch 28i.

In my house, its 2 adults, both primarily shower users. So I guess a combi works ok for that small need. Although we both can't shower at once. Not sure if I can add a tank to relieve that problem?

But for the Ex's house, they bath alot. So wondered if I need something other than a normal Combi, as there is a tank in the loft, downstairs boiler and a immersion in the airing cupboard that could be replaced.

a householder's opinion:

in a house that already has a tank and cylinder, you can put in a new conventionl boiler without having to change anything else. Although most are unvented (pressurised) there are some open vented boilers around as well.

A modern boiler heats up a modern cylinder in about 20 minutes, so by the time one person has had a bath, got out and towelled off, it will be ready for the next.

thanks. I've emailed Agile Tony to see if he can come and sort me out

there are high flow combis around that do two showers.
