Mine is some 90s looking 'Ferroli' boiler, looks pretty naff really!
Also has the boiler been serviced before you moved in?
You should have a service form, showing it's had it's annual service & safety check.
How important is a yearly service? Mine hasn't been serviced for some years. Should I really get a man in ASAP?
No way you can be liable for getting the boiler fixed as a tenant.
