Grant Vortex Combi

Due to the vast range of stock we carry on our vans we are able to repair 99.9% of all boiler, cooker and stoves on the same day. We look to get to our regular customers the same day or the next day at the latest, so being without heating and hot water is something our customers never experience.

Through years of experience we have devised a van stock to suit all popular appliances so having the wrong spare or no spare at all is something that hardly ever happens. This means from calling us to having your appliance back online is a matter of hours not days. This we feel is where we stand out from the crowd and excel in our field as being cold and having no hot water is something no one wants, also in the unlikely event we do not have the part we do not charge for the second visit to have to comeback unlike most other companies.

Oil Based heating and cooking systems run on domestic kerosene. Oil based boiler should be serviced every 12 months and cooking systems such as Agas or Rayburns every 6 months. It is important to keep them regularly serviced otherwise sooty deposits can build up and they no longer work as efficiently. It is also important to keep heating systems regularly inspected to ensure that they are running safely.

We also design and complete full oil-fired and/or renewable technology central heating systems. Here at Southwest Oil heating Specialists, not only are we specialists in the field of oil-fired heating, but like you, we are wanting to help the environment for future generations. All of our engineers are experts in designing and installing tailor made system to meet your needs. We have detailed below two of our most popular type systems.

Again working very closely with one of the UK’s top manufactures, Grant UK, ( for whom we are officially accredited installers ) we feel produce some of the best renewable technology on the market. Therefore as we only fit the best, we like to promote the best.

Solar Thermal Water Heating Systems

Solar Thermal is a clean and highly efficient means of using renewable energy from the sun to provide the hot water used in the home. Many people believe that solar thermal only work in the summer, however, this type of free energy is available throughout the year. From May to September, Grant Solar Thermal could produce 100% of the energy required for heating your domestic water (see right). Both the Grant Aurora and Sahara collectors operate not just with direct sunlight, but also diffused sunlight, so they even work on cloudy days.

All components within the Grant Solar Thermal Range are regularly tested under simulated real conditions to ensure customers receive a product of the highest quality and reliability. Grant Solar Thermal systems come complete with a 5-year manufacturer’s warranty.

Key Features

1. Complete Solar Thermal kits available, starting from one-collector systems.
2. Generates up to 70% of your hot water requirements annually
3. Collectors carry the Solar Keymark approval, allowing homeowners to access the Renewable Heat Incentive (RHI) from Summer 2011
4. Integrates easily with conventional water heating systems, including combination boilers when utilizing the Grant CombiSOL
5. Two styles of collector available: *Aurora* in a high quality silver anodised finish and *Sahara* in an exceptional bronze finish
6. Both feature 4mm self cleaning glass.
7. Collectors incorporate copper absorber with Sun-select coating, giving better solar absorption
8. Unique serpentine pipe configuration within the collectors ensures maximum heat transfer and eliminates air locks
9. On-roof, in-roof and flat-roof collector mounting systems, both in portrait and landscape.

Air source heat pumps

If however you feel you would like to have a complete stand alone renewable heating/hot water system offering the choice of having no boiler what so ever, which can also replace existing boilers, have you thought about having an air source heat pump installed.

Air Source Heat Pumps use basic thermodynamic principles to convert latent/sensible heat (contained within the ambient air) into heat energy that can be used to provide heating and hot water. In this respect the device can be classified as a renewable energy source because the heat in the ambient air is replenished by the sun.
There are two types of ASHP- *air to air* and *air to water*.

Air to air heat pumps release the captured energy through an air heat exchanger, which is then forced (by fan) around the dwelling through trunking, or directly into the room. Most commercial buildings use this type of heating medium. The Grant Aerona is the air to water type. Air to water heat pumps release the energy into a water circuit which is then used in a wet heating system (radiators or underfloor).

A good choice for home heating

Upward spiraling energy costs and advances in heating technology, have positioned Grant Aerona Air source heat pumps as a very realistic alternative to the conventional fossil-fueled heating system.

Compared with other domestic heating methods, a Grant Aerona heat pump can benefit homeowners by creating annual savings on fuel bills, as it can deliver up to 5.8kW of energy for every 1kW used to run the unit (this figure is dependent upon the model and water/air temperature. It also means that homes have a lower dependency on fossil fuels, making them less susceptible to rising fuel prices. Home heating in the UK additionally accounts for some 30% of carbon emissions. Grant Aerona heat pumps can help reduce the amount of these harmful gases being released into the atmosphere, therefore lowering the homes carbon footprint. The units are available as five MCS Approved *single phase* units, with outputs ranging from 6.5kW-15.5kW.

Key Features

1. Exceptionally high COP’s up to 5.8.
2. Factory fitted weather compensating device with dual temperature control, allowing the unit to perform more efficiently.
3. Factory fitted 3kW Immersion back up, designed to operate when demand for the ASHP exceeds its stated output e.g. extreme cold weather for long periods.
4. Legs ensure heat pump is protected against snow build up, leaves and flood.
5. Base tray heating element to stop ice formation in cold weather conditions.
6. High quality powder coated external case with condensate deflector.
7. Compact design with common footprint across all models
8.  Two year manufacturer’s warranty, with an option to extend this to five-years.

With an established history of over 30 years designing, manufacturing and supplying a wide range of highly efficient and reliable products, Grant has become a firm favourite for many people when choosing a new or replacement oil-fired boiler.   Today, Grant’s range of Vortex oil-fired condensing boilers tops the Government SEDBUK Efficiency Database and is the market leading product in this sector.

A new approach to oil-fired heating

The name ‘Grant’ has in recent years become synonymous with highly efficient oil-fired central heating appliances. Designs like the ‘Multi Pass’ boiler achieved efficiency levels far in excess of any UK or European Standards and have helped thousands of homes to reduce their annual fuel bills. So it will come as no surprise to see Grant yet again leading the way with the Grant Vortex oil-fired condensing boiler range.

Despite the sophisticated technology employed in the development of new products, Grant’s design engineers have kept true to the original Grant concept of simplicity in installation and maintenance which are essential ingredients of today’s heating systems. Grant products are manufactured from the highest quality materials and designed not just to meet, but to exceed all relevant performance and environmental standards.

Voted ‘Which Best Buy 2008′

Vortex Pro Internal Combi Condensing Range

For almost two years Grant has been working behind the scenes on brand new electronic versions of the successful Grant Vortex Combi Range with the aim of incorporating as many of the additional features and benefits customers have requested, whilst bringing the technology installed in these appliances up to the minute. The new models now include internal frost protection, neon diagnostic indicators and a factory fitted internal condensate trap (this can be sited externally if preferred), which is designed to make installation and servicing easier.

The Grant Vortex Pro Internal Electronic Condensing Combi’s are available in three sizes, 21kW, 26kW and 36kW.

Unique Design

Best Condensor Boiler 2008

Grant Vortex Pro Combi’s feature much larger plate heat exchangers which due to their low water content and larger surface area, vastly increase the hot water performance available. Mixing valves are pre-set at 50°C, controlling accurately the hot water draw off temperature from the boiler. They also feature a low system pressure cut off switch, enabling the combi to protect itself in the unlikely event of system water loss. Additionally, there are two very accurate electronic temperature controls which allow the boiler to operate in condensing mode on central heating, whilst maintaining its instant hot water production.
