Ravenheat boilers - affordable and efficient

Ravenheat boilers - high efficiency Ravenheat boilers

COMBISTORE

COMBISTORE is a variant of Ravenheat's COMBIPLUS, adding a 15l store to the system, to maximise the savings that ENERGYCATCHER offers.

The 15l store means that while in central heating mode, ENERGYCATCHER can store more of the latent heat that it recycles from flue gasses, ready to be used when there is DHW demand. The ability to store a larger volume of pre-heated water increases the potential for ENERGYCATCHER to save money and to ensure that the system is operating at optimal efficiency for longer.

COMBISTORE brings together a CSI 120 (32kW) or CSI 150 (42kW) high efficiency combination boiler with ENERGYCATCHER technology, and a 15l store to deliver powerful hot water performance, with increased flow rates and savings of up to a further 52% on the cost of heating water.

  • COMBISTORE takes only 20 minutes extra to install, but will give your customers outstanding savings well beyond those of a typical condensing boiler. The ENERGYCATCHER unit fits flush with the top of the boiler, so no unsightly pipework, just a neat finish. Because there are no moving parts in ENERGYCATCHER there is no maintenance requirement. Quality and reliability come as standard through the use of the highest quality components and an all brass manifold for extra durability. All of this is backed up by our standard three-year guarantee, which can be extended by a further two or even five years.

  • Both COMBISTORE models offer powerful performance suitable for two or three + bedroom properties, delivering both heating and hot water, whilst also reducing your heating bills significantly. By incorporating the award-winning ENERGYCATCHER, we help you to get more useful heat for each pound you spend on fuel. These models can also be used in one bedroom properties where there is an exceptional demand for hot water.

    Both COMBISTORE models are affordably priced and will typically pay for themselves within two to four years, making them an excellent investment. You could save as much as 30% on your gas consumption, which will help to bring down your gas bills and get more usable heat for each pound you spend. In standby mode CSI boilers are also energy efficient with standby losses of just 3W.

    A fully insulated case also ensures minimal noise, so you're less likely to hear the boiler working in the background. Our built-in frost protection also allows the boilers to be sited in enclosed outside spaces, such as a garage.

    For complete peace of mind COMBISTORE boilers are backed up by our standard three-year manufacturer's guarantee covering parts and labour. We offer guaranteed same-day or next-day service callouts, to ensure that if there is a problem, it's resolved quickly and with minimal disruption. You also have the option to extend the guarantee by a further one or two years.

    If you are in an area which is not on mains gas, COMBISTORE is also available in LPG models.
  • Achieve Code for Sustainable Homes Levels 3 and 4

    COMBISTORE has already been used by numerous housebuilders and social landlords to improve efficiencies in line with the requirements of the Code for Sustainable Homes (CfSH). The ENERGYCATCHER technology that is featured in the COMBIPLUS helps you to achieve Level 3 of the Code, while using COMBISTORE in conjunction with solar thermal can reach Level 4 or greater, without the need for additional measures.

 Because COMBIPLUS maximises the amount of useful heat gained from each pound spent on gas, it's the ideal solution to help combat fuel poverty by saving up to 30% on heating bills, with a further 52% savings on hot water.

    The initial capital cost of our products is much lower than many of our competitors, making it more cost effective for you to undertake large scale retrofit projects across more of your housing stock. The simplicity of ENERGYCATCHER technology makes it straightforward to install and takes only 20 minutes longer than a normal combination boiler, again keeping costs to a minimum. Because ENERGYCATCHER reduces pluming, it often removes the need for a separate plume management kit.

    For projects where greater design flexibility is required, COMBISTORE reduces the Dwelling Emission Rate (DER) of a property and can be used to offset the choice of other materials which have lower efficiencies or higher losses.

    According to the Energy Saving Trust, an average three-bedroom family home could save as much as ￡300 per year, when upgrading from a G rated appliance (less than 70% efficient) to a Band A appliance, such as the COMBISTORE, with heating controls. COMBISTORE reduces bills even further because it has ENERGYCATCHER built in.
  • Our wireless controls not only maximise the efficient operation of the boiler, they also allow householders to match their heating requirements to their lifestyle so that the home is at the desired temperature exactly when they need it. The WHITE HEAT range can be fitted with our optional 7-day combined room thermostat and timer, with programming options that split in to 24-hour periods, with up to 48 individual time slots. If your customers require simplified operation, there are also pre-defined “Comfort” and “Economy” settings.

    The transmitter, with its easy-to-read back-lit digital display is common to both models and has an  operating range of up 30m from the receiver unit. It can be wall mounted, or free standing and should ideally be placed approximately 1.5m above the ground in order to have maximal effect.

    The RHVT 1 includes a receiver unit which can be fitted away from the boiler, while the RHVT 2 has a receiver that is easily fitted in to the control panel of the boiler and is the same size as the standard clock which it replaces.

    Both types of receiver have a built-in manual override and LED display. Once set, the RF transmission code is set using dip switches, making it unique and preventing interference from any other RF signals.
  • The CSI 120 and 150 can be fitted with either a 100mm standard concentric flue, a 125mm flue duct or a twin eccentric flue duct, all in either horizontal or vertical configurations depending on the application. A standard one metre (60/100) horizontal flue kit is supplied separately and can be extended up to a maximum of 8 metres horizontally, or 13 metres vertically (without bends or elbows).

    The 125mm concentric flue system allows even greater siting flexibility, with runs runs of up to 26 metres.

    Finally, the eccentric flue ducting is ideal for covering extremely long distances and when used with a custom Ravenheat connector can extend the total flue run to 43 metres air intake / exhaust.
