Johnson and Starley specialises in design and production of a comprehensive selection of ventilation and heat recovery equipment where installation of ductwork is not practical.
Renoxtra Sedbuk Band A combination boiler
RenoXtra high efficiency combination condensing boiler from Johnson and Starley features a new gas saver module built into the cabinet of the boiler and provides additional system efficiency.
Buildings need to be ventilated so that stale, moisture-laden air is replaced with fresh air and the most efficient method is to use a mechanical ventilation system with heat recovery.
Johnson and Starley is a market leader in this technology and their Whole House Mechanical Ventilation System, with heat recovery, will both eradicate condensation and provide a cleaner, fresher living environment.
Stale, moist air is extracted from 'wet' rooms through grilles and passed across an aluminium plate heat exchanger to remove the heat.

Reducing air leakage through the building envelope
Johnson and Starley specialises in the design and production of a comprehensive selection of ventilation and heat recovery equipment where the installation of ductwork is not practical.
The residue is exhausted to atmosphere.
Fresh, filtered supply air is then drawn across the heat exchanger, warmed by the retained heat and distributed through ceiling mounted grilles to 'dry' rooms.
Air-streams are separated to avoid cross contamination and up to 70% of wasted heat energy is recovered.
The company also offers a number of different heat recovery solutions which are BEAB approved and comply with Building Regulations - Approved document F.
All models come complete with the JS6 speed control.
On the HR150 it is incorporated within the casing and is pre-wired.
On the HR100 and HR200 it is supplied loose for remote siting.
Electronic filtration is an optional extra and 95% of particles down to 1 micron will be removed including pollen, cigarette smoke and house dust.
The larger HR600 unit is designed for use in commercial applications such as pubs and clubs where there is a requirement for ventilation and improved air quality.
Meanwhile, the company's brand new generation of Central Extract Ventilation Systems has been introduced in support of the latest version of Part F of the Building Regulations and the Good Practice Guide 268 for domestic ventilation.
Two multi-spigot systems, one featuring state of the art EC fan technology, as well as an in-line model, have been introduced to meet all specifiers' and contractors' requirements.
Designed for use in new build and existing dwellings, these systems are designed for installation in the roof space or ceiling void.
Their slim design and the ability to mount them in different positions provides the contractor with complete flexibility.
Commissioning can be carried out with the systems running and once balanced cannot be interfered with by the occupier.
All units, however, have a fan speed controller with option to be conveniently mounted remote and allows ventilation performance to be increased by up to 25%, in accordance with the Building Regulations.
The C300 and C300 Premier central extract systems are designed for whole house ventilation.
They are capable of achieving airflows of 300 m3/hour.
The C300 Premier includes an EC fan for even more energy efficient operation and lower running costs.
It is ideal for highly specified installations.
For smaller dwellings, the C180 in-line system provides spigots for one duct in and out.
It has an AC fan and provides an airflow of up to 180m3/hour.
All the new central extract systems have an integral filter that is easy to remove and protects the internal components.
Additional controls, such as humidistat and air sensors, together with ducting kits are also available. Request a free brochure from Johnson and Starley ...
