Boiler recommendation and cost

Hi.
I have a 1 bedroom flat in London which I rent out to tenants and looking to replace the 10+ year old Valliant boiler as it has had various parts replaced over the years.
The purpose built flat has 3 radiators and a towel one in the bathroom.
The flat is energy efficient built in 2007 so rarely do you need the heating on but obviously the hot water is a must so don't want it breaking down again.
A local plumber has suggested a Baxi Main Eco Compact 25Kw boiler fully fitted for £1600.
Is this a good price or should I look for a less powerful one for this energy efficient flat?
Thanks

I've budgeted £2.5-3k for a new boiler fitted in my flat. So I'd be happy with your quote

A boiler should last more than 10 years, with maybe just a couple of new parts, so this one sounds like a dud.
However £1600 fully fitted sounds a very good price.1 -
1, Combi boilers are generally sized for their ability to provide a reasonable quantity of hot water pretty much on demand. On this basis 24 / 25 kw is about the right size.
2. Modern boilers alter the rate at which they burn gas ("modulate") to cope with greater or lesser demand. Make sure the boiler you get can handle a wide range of power output, from, say 1/4 of it maximum rating to its maximum rating. Thus it won't be running full blast just for heating. Some can be "range rated" within their maximum rate, so the central heating output can be fixed at, say 12 kW maximum.
3. Make sure modern controls are included within the quotation. New boiler installation requires modern controls, and, for a rental , they can make a difference (albeit small) to the EPC rating of the property.1 -

New boiler installation requires modern controls, and, for a rental , they can make a difference (albeit small) to the EPC rating of the property.The Baxi MainEco will modulate down to 6kW from a maximum of 20kW for heating. Not a brilliant modulation range (my Viessmann will do 3.2-24kW). With only 3 radiators, even 6kW is going to be too much, so I would imagine the boiler will short cycle a fair bit. For comparison, I have 8 radiators, and much of the time, the boiler is ticking over at around 4-5kW.Well worth fitting a programmable thermostat that allows for different temperatures throughout the day/week. As the Baxi is OpenTherm compatible, there is a decent selection of thermostats available - Some come with an app (if you really want to go that route).With a new boiler, it is worth fitting larger radiators - This will enable you (the tenants) to run at a low flow temperature which means higher efficiency and lower gas bills.
Her courage will change the world.
Treasure the moments that you have. Savour them for as long as you can for they will never come back again.0 -
