Vaillant ecoTEC Sustain 34kW Combi Boiler
The Vaillant ecoTEC Sustain 34kW Combi Boiler is their best performing domestic hot water boiler in the ecoTEC sustain combi range, which combines high flow along with the same dimensions and engineer friendly design of the smaller 24kW and 28kW boilers. Designed specifically for the precise specification requirements of social housing and heating fitters, this 34kW model provides high flow domestic hot water on demand with no call for extra space or hot water storage.
Features and Benefits: ecoTEC Sustain 34kW Combi Boiler
Precision Manufacturing: Produced and quality-checked at Vaillant Belper, Derbyshire, UK.
Hot Water Performance: It can manage a substantial 34kW DHW output. This gives a quick 14.1 litres per minute at a 35°C change in temperature. This is really useful for high-flow showers and when you need to fill a bath in a hurry.
Stainless Steel Heat Exchanger: Manufactured from high grade stainless steel, which is known not only for its reliability and longevity, but for its resistance to corrosion and scaling whilst giving the best heat transfer.
Dimensions: Sized at 720 x 440 x 338mm for a direct swap means these boilers have the same footprint as existing ecoTEC pro boilers and use the same connections, so they can be installed and connected to existing Vaillant flues with minimal refitting.
Installer Features: Direct access to key components from the front and removable side panels make it possible for quick servicing in compact positions and to install the unit.
1:4 Modulation Ratio: Automatically reduces boiler heating output to lower firing levels when there is a reduced demand in milder weather, this helps the boiler to use less gas and to prevent short-cycling.
43 dBA Quiet Mark Certified: Operates at a low sound power level, which we would carefully consider when installing in bedrooms and airing cupboards.
92% ErP ‘A’ Efficiency: With a modulating low-NOx burner and fan, plus a Grundfos pump (NOx Class 5), this is a boiler you can rely on when you need it the most.
Interface: An Illuminated LED blue-on-black high contrast multi-info display showing the units status and diagnosis for fast fault finding.
Condensate Trap: Accessible at the base with a new internal back up and safety siphon to protect against blockage when the conditions outside drop below zero.
EBUS & Hybrid Ready: Native eBUS protocol that gives connection to Vaillant’s range of smart controls and aroTHERM heat pump hybrid systems.
