Product Description

Designed and manufactured by Firebird, the Envirogreen Slimline Heatpac C35 is a compact regular oil boiler that can be installed in the garden. To protect it from any weather thrown its way, the Slimline Heatpac C35 has a high-quality weatherproof coated casing.

Firebird have designed this boiler with efficiency in mind, as shown by its 93% seasonal efficiency rating and ErP A-rating for heat. An output of 35 kW is ideal for larger homes with 2 or more bathrooms and a high demand for heating and hot water. For smaller to medium sized homes, the range also includes outputs of 20 kW and 26 kW.

This boiler is available with either low NOx or blue flame burner options, with the burner featuring a full diagnostic control box. The unit is fully-insulated and acoustically designed for ultra-quiet operation, a patented heat exchanger design and removable sides for ease of access, factory fitted expansion vessels and circulating pump, PCB control using highly accurate thermistors with an anti-cycling function, frost protection stat, low pressure switch that protects the unit in the unlikely event of a system water loss, stainless steel terminal guard and the piping can be carried from the back or underneath the unit for flexibility in where it can be placed.

Regular boilers are installed as part of a heating system that includes a boiler, extended controls, hot water cylinder, often fed by a cold water storage cistern in the loft, and a feed and expansion cistern, also located in the loft. All of these parts mean that they’re most suited to larger homes with space to spare.

Available with a 2 year warranty as standard, with the option to upgrade to a lengthy 10 year period, you can be confident that the Envirogreen Slimline Heatpac isn’t going to let you down.
