Condensing combination boilers for larger homes

ecoTEC
Space heating for larger dwellings, with hot water to match — Vaillant’s ecoTEC exclusive condensing combination boiler.
Vaillant’s ecoTEC exclusive condensing combination boiler can provide space heating and domestic hot water for larger domestic properties. There are two models, with DHW outputs of 32 and 38 kW. These boilers have a SEDBUK band A rating and a wide modulation range, so they operate in condensing mode for longer to maintain high efficiency at lower outputs. They incorporate an electronically controlled modulating pump to improve overall efficiency. A new filling loop makes installation easier, and there is a new backlit clear text display. Other features include 2-stage frost protection and a simple push-fit flueing system in a wide range of lengths. Both boilers are compatible with all Vaillant’s controls, such as the VRC 430 weather compensator and 360F programmable room thermostat, which allow 2-way communication between boiler and central heating, making for a more efficient and intelligent system.
