Given the range of property types and sizes with the UK’s housing stock, the requirements needed from a heating and hot water system will differ from job to job. Worcester’s Martyn Bridges explains the importance of considering an individual properties’ requirements before automatically turning to a ‘go-to’ product... HEATING & PLUMBING MONTHLY DECEMBER 2013 43 There can be a tendency among installers to rely on a few select ‘go-to’ products when surveying a property for some potential heating installation work. While manufacturers are delighted when an installer chooses to stick with their brand, it is important for installers to adopt an open mind when it comes to selecting the right product from this brand as this will help ensure the needs and requirements of the customer are met. Given the ever growing range of technologies available to them it is important installers are aware of different products and understand the situations in which they are most suitable. In addition to the size of the property, it is also essential to establish the needs of the homeowner and also the demands being placed on the heating solution. For example, does the homeowner want a heating and hot water system where the hot water is produced instantly on demand with perhaps a lesser flow rate that a storage system? Or are they happy to wait for the hot water storage cylinder to heat up, however, once hot a number of outlets can be operated simultaneously? Once the installer has the answers to these questions they can usually establish if the property is more suited to a combi boiler or an alternative option. HOMEOWNER NEED This is where looking at a manufacturers’ extensive product offering is beneficial to the installer as there will often be a perfect product available for a particular situation and homeowner need. There is undoubtedly a growing demand for instantaneous and continuous hot water products and manufacturers are developing ranges which offer a solution to the demands of larger domestic and commercial appliances. With compact dimensions and outputs of up to 50kW, instantaneous water solutions are ideal for domestic applications with a high demand for domestic hot water such as larger homes or guest houses and, therefore, worth thinking about when faced with a residential project of this size. Instantaneous water heaters can be cascaded with up to 12 appliances to offer a combined flow rate of up to 250l/min. This makes the technologies suitable for commercial applications with either consistent high demands or very high cyclical demands for domestic hot water. As such, getting to grips with this product could lead to business opportunities for installers within the hospitality and retail sector. Also with this form of heating there is no requirement for stored water tanks within the property saving space and reducing the risk of Legionella contamination which also makes it ideal for fitting in hospitals or health clinics - another profitable sector for installers to add to their business. A condensing water heater is also compatible with a pre-heated water supply, making it an ideal partner for solar thermal or heat pumps, should the homeowner wish to one day ‘go green’. I believe the popularity of this product is set to rise as interest in renewable heating solutions continues to grow. STRONG DEMAND Another alternative to ‘traditional’ heating systems is a storage based system comprising of a hot water cylinder. Even with the increasing sales of combi boilers, demand for hot water cylinders is still very strong, particularly among homeowners with larger properties and multiple bathrooms. Or for those forward-thinking homeowners with an eye on solar thermal collectors as a supplementary source of hot water alongside a boiler, meaning a cylinder-based option is another product worthy of consideration before the installer turns to any alternatives. The role of a hot water cylinder in the overall efficiency of a domestic heating system is extremely important. Hot water cylinder technology has undoubtedly progressed, allowing greater efficiency than ever before, with the heat loss of the cylinder and the heat up times reaching new levels. Typically, a typical single coil cylinder works on the basis that its entire contents are heated to a prescribed temperature, to cater for the required hot water comfort of the property. The combination of rapid re-heat and insulation minimises the energy and heat that is wasted - consequently keeping bills to a minimum. This feature has grown in significance since the introduction of the requirement for greater insulation levels under the revised Building Regulations. HOT WATER STORAGE SOLUTIONS As the drive towards a more widespread adoption of renewable technologies gathers pace, greater emphasis is placed on the need for hot water storage solutions within the home. Therefore high performance cylinders have been specifically designed to offer maximum energy and cost savings, while meeting our customers’ demand for quality, reliability and peace of mind. With such an in-depth product portfolio available to today’s installers it is imperative to look beyond a select few familiar technologies and establish the individual installation requirements to ensure the most suitable system is installed. Only by making such considerations can the homeowner be given assurances that their heating system will perform at its peak for as long as possible. Not only that, but being able to prove to customers that they have their best interests at heart, is also likely to increase the chance of repeat business. Diversifying into new sectors will allow installers to capitalise on a full range of business opportunities, something which is imperative in this ever evolving industry. Being able to turn you hand to the installation of everything from combi boilers to hot water cylinders will ensure the installer’s business is always one step ahead of the changes and can remain as profitable as possible. enquiry number 137 There is a growing demand for instantaneous and continuous hot water products
