The Welcombe Hotel: a refurbished heating system means better energy efficiency

A Welcombe change

Over the course of two years, Danny Bulch, director at Cedar Green Projects, replaced the boilers, gas fired water heaters and calorifiers in the Welcombe hotel, spa and golf club with new equipment. The main challenges of the project were carrying out refurbishment during peak heat requirements in winter; overcoming access issues to the plant room; and accommodating different fuel options.

Heat pumps on the rise

Renewable technologies are becoming more commonly applied in UK homes, with more householders installing solar panels than ever before. But when it comes to sources of heat, most houses are still fitted with ‘traditional’ boilers, and many homeowners are unaware of the alternatives available. However, 2018 looks to be a turning point, with heat pump applications increasing because of the benefits they offer.

Beside the seaside

The Victoria Hotel in Sidmouth, part of the Brend Hotel Group, promises its guests that: “From the moment you step through the original carriage portico, you will be surrounded by warmth and refinement.” Where the exquisite décor and four-star service provides the refinement, a new A-rated efficient boiler from Potterton Commercial is now providing the warmth.

Optimise your district heating

While district heating systems may have had something of a chequered history in the UK, the last few years have seen a considerable resurgence in their popularity. This is in line with the move to central energy centres, which make it easier to deploy both traditional and low carbon heat sources together.

Signed, sealed, delivered

According to the Building Engineering Services Association (BESA), offsite construction currently accounts for at least 3% to 4% of the UK construction sector. However, the cost and time savings and quality control benefits associated with this method will no doubt see it grow exponentially in the next decade.

Powrmatic, Paul Fox, destratification, warm air heating

Destratification for efficiency

Most MBS readers will be familiar with the phenomenon of thermal stratification, a frequent occurrence in high-roofed buildings where the natural buoyancy of warm air results in its accumulation at high level. Heating this unoccupied area of the space is clearly inefficient, exacerbated by colder air at high level being pushed downwards into the occupied zone by the warm air, increasing the demand for heating.

Quality control

For commercial buildings, such as offices, hotels and leisure centres, a consistent hot water supply is a business-critical service. If a system fails, it can quickly force a business to shut its doors until a solution is found. Even more critically, you only have to look at the recent spate of legionella outbreaks in hotels around the UK to see the devastating impact a failure in water maintenance can have on a business. However, despite this there are still a large number of business owners who do not have a programme in place that meets the demands of their site.

To VE or not to VE

One of the key recommendations to come out of the Dame Judith Hackitt’s Independent Review of Building Regulations and Fire Safety was for a clearer, more transparent and more effective specification process to put an end to cost-cutting compromises.

Be prepared

In the last few years, the energy management landscape has changed considerably and will undoubtedly change again in the future.

Making the Grade

September traditionally hails the start of heating season, where thermostats click in, BMS systems relay information and commercial boilers fire into action to warm occupants feeling the first chilly morning of the autumn.

The heat is on

The UK has so far been successful in achieving interim targets for carbon reduction. But now the low hanging fruit is scarce, it’s time to tackle the big challenge head on - decarbonising our heat. Karen Fletcher looks at the options and the hurdles ahead.

Sentinel’s triple power

Sentinel Commercial’s water treatment chemicals now have more than triple the power in protection of commercial heating systems, with each drum able to dose systems over three times larger. The new ‘Triple Power’ formulations of Sentinel X100 Inhibitor, X300 Cleaner (for new systems), and X400 Cleaner (for older systems) mean smaller or fewer drums are required for bigger jobs, a development which saves significant costs, waste and storage space, and makes for easier transportation, handling and dosing.
