Firebird Silver Pac: an external oil boiler option
Silver Pac is built to live permanently outdoors, in a weatherproof casing, for properties where there simply isn't a garage or utility room to house a boiler. It suits smaller cottages and outbuildings-free plots.

Detail that affects your quote for the Silver Pac external boiler
- Fully weatherproof casing designed for permanent outdoor siting
- Suits period cottages with no spare internal plant room
- Same OFTEC tank, line and fire valve rules as internal installs
- Winter servicing is done outdoors, so access matters
- A practical answer where internal space is the limiting factor
How we read the Silver Pac external boiler on site
Because the whole unit sits outside, the casing and burner compartment are engineered against rain ingress and frost, and the flue and electrical connections are routed accordingly. Servicing still follows standard OFTEC annual requirements, though the engineer works from outside rather than in a warm plant room, so winter appointments are planned with that in mind. Oil supply and fire valve requirements are the same as any other oil installation.
Who should undertake the work
- Gas appliance work must be completed by a suitably qualified Gas Safe engineer
- Oil appliance work should be completed by a suitably qualified OFTEC technician
- Jamie Crawford Heating states both Gas Safe and OFTEC registration
Where we deal with this
Questions we get asked
- Does it need extra weather protection in an exposed spot?
- A very exposed elevation may benefit from a windbreak or careful positioning, which we'd assess on survey.
- Is an external boiler noisier?
- Being outdoors, any burner noise is less noticeable indoors than an internal unit close to a living space.
