HM85TC Evo Combined Gas Fired Condensing Boiler and Water Heater
Combined gas fired condensing boiler & water heater with stainless steel heat exchanger.
- Heating and hot water from one unit saves space, reduces energy use and speeds up installation
- Operates in most efficient mode (condensing) for both heating and hot water
- Low maintenance with no anode protection required
- Reduces legionella risk due to water stored at > 60°C
- Corrosion-resistant stainless steel heat exchanger and tank reduces maintenance and increases system lifespan
- Suited to high demand and critical hot water premises such as hotels and hospitals
- Easy to use standardised controls using ACVMax control system
- Combine with Evo S condensing boilers or Smart cylinder for highly efficient heating and hot water performance all from one manufacturer
- Suitable for vented or unvented systems (optional Systempak 3 unvented kit required.
- Kit includes 25L expansion vessel, tundish, pressure control valve, combined pressure reducing valve and mounting bracket)
- Supplied with LPG kit for simple on-site conversion
- Supplied with factory fitted T&P relief valve
- Improved access for service and maintenance
- 5 year warranty*
Tank-in-tank technology
- Fast heat up
