Wall-hung condensing boilers with flexible flueing are growing in popularity.

To repair or replace?

Upgrading heating plant and installing a new boiler is a major purchase for organisations. GRAHAM WILLIAMSOn looks at why, despite the initial outlay, it is better to replace rather than continue to repair ailing heating plant.

Enjoying the benefits of prefabrication

Designers, contractors and end users should make much more use of prefabricated boiler and hot-water plant, says Ken Percival.

Common-sense approaches to energy-efficient boiler control — Julian Miller.

How controlling boiler plant can cut fuel bills by 40%

Common-sense methods of controlling boiler plant are frequently not exploited. Julian Miller explains how energy savings of at least 20% and as much as 40% can be achieved.

Lochinvar
A Lochinvar EPW15OCE Efficiency Plus water heater and LST70 storage tank complete with direct stacking frame replaced the existing kitchen hot water system at the Cedars School in Gateshead.

The hot topic of water heating

David Pepper considers the driving forces for efficient water heating and the opportunities in refurbishment projects.

Keston
A modular prefabricated Keston boiler rig is combined with high-efficiency calorifiers to achieve a heating and hot-water solution.

Extending efficiency to design and installation

Keston’s prefabrication service is, says managing director Nick Stevenson, designed to ‘take the headache out of designing a heating system, by way of bespoke prefabricated, pre-assembled boiler-plant rigs that are designed individually to meet the exact needs of the project and dramatically cut on-site installation time’.

Stokvis
Wall-hung condensing boilers with outputs up to 100 kW have been launched by Stokvis.

Rycroft

Rycroft develops hot-water specification program

Rycroft has developed an interactive computer program that enables water-heating systems for major projects to be selected and specified in a matter of minutes.

Spirax Sarco
Efficient and effective heating of the L’Oreal factory in Wales is being a achieved using a pair of Spirax Sarco steam-to-hot-water heat exchangers using process steam.

Factory heating integrates efficiently with process steam

Such is the efficiency of two Spirax Sarco EasiHeat engineered systems installed to replace a large boiler providing space heating at the L’Oreal factory in Wales that an installed capacity only a quarter of what was used before is adequate for even the coldest winter days.

Water heater
State Water Heaters’ commercial balanced fanned flue water heaters have efficiencies exceeding 90% and flue runs up to 7 m.

Water heaters designed for longer life

A novel engineering feature in the State range of water heaters prolongs life, reduces heating costs and premature replacement.
