New Renoxtra boiler features gas saver module

The new RenoXtra high efficiency combination condensing boiler from Johnson and Starley features a new gas saver module built into the cabinet of the boiler and provide additional system efficiency.

The new module works by re-cycling flue gas heat, which is normally wasted and expelled to the atmosphere, extracting virtually all the energy from the incoming gas supply.

Reclaimed energy is stored in the unit and is used to pre-heat the incoming cold water.

This results in extra domestic hot water (DHW) efficiency Lower gas consumption, running costs and reduced carbon emissions.

It can also help to reduce DHW delivery response time.

RenoXtra has a one-piece stylish appearance and to ease installation by reducing the lift weight; it is delivered in modular form.

The complete assembly is mounted on a wall jig that contains the necessary fittings to connect the gas saver to the main body of the boiler thus completing the fully integrated RenoXtra.

Test work carried out has demonstrated substantial DHW energy saving benefits of the RenoXtra condensing boiler.

It also has the ability to reduce emissions and can help in reducing the problems associated with pluming.

The RenoXtra high efficiency combination boiler comes in 30kW and 37kW models.

Testing to BSEN 13203 has demonstrated additional gas savings of approximately 11% in summer mode and up to 40% in winter mode when the central heating demand produces more condensate that enables higher rates of heat transfer and heat recovery.

Flue routing of the RenoXtra is completed using standard kits, which are supplied as standard with the RENO range.

The RenoXtra with integrated BRE approved Zenex "cool-flue technology" is expected to be the world's first thoroughbred SEDBUK A combination boiler that qualifies for the appendix Q rating on the SAP database.
