Best combi boiler right now?

No idea whether to go with Worcester Bosch, Valliant, Ideal or another brand for a combi boiler replacement. What do you all recommend for a 3 bed detached with 2 bathrooms?

"Try Viessmann or Atag, really good boilers, and currently cheaper than Worcester Bosch and Vaillant. Don't bother with Ideal."

"Hi I highly recommend vaillant boilers, 10 years warranty, unfortunately they are probably most expensive on the market but you do get what you pay fo, the customer service is brilliant if they do need to come out in the warranty period they will be vaillant engineers not contractors
Hope this helps
Thanks lee bucknall"

"System boiler with a cylinder
If you opted in with a combi you may have flow rates issues and it all depends on the flow rate of the cold water NOT the pressure
For example if you flow rate of your cold water is 16 lites per min then a lot of combi has a max flow rate of 14 lites depending on the model all boiler do the same thing they boiler hot water


if your running two bath at the same time you reduce your flow rate by half again would strongly advise you get a assessment done before you commit
Hope this help"

"Personal choice as an installer and value for money in my book is the ideal combi.
They are reasonably priced offer good warranty and the parts are not the most expensive and most importantly are readily avaliable when thing's do need to be changed...
The manufacturer side of things is good to as they are a big enough to have lots of engineers on the road to respond quickly to honour the warranty repairs."
