Mains pressure hot water system to suit either sealed or open vented systems

A total hot water package; The BoilerMate BP is an open vented thermal store that does not require expensive safety valves and it provides mains pressure hot water. The BoilerMate BP is suitable for use with a gas or an oil boiler and the heating system can be either open vented or sealed. It is also suitable for upgrading existing traditional hot water systems.

Mains pressure hot water; BoilerMate BP thermal stores provide;

• Mains pressure hot water giving ‘power shower’ performance.
• Up to 22 litres per minute filling a standard bath in 3-4 minutes.
• A dry roof space eliminating the risk of freezing pipes/tanks in winter.
• Increased system efficiency, reducing running costs.

Low cost installation/maintenance; Easy to install BoilerMate BP can be fitted to existing systems, including the existing boiler and controls, where appropriate. Unlike unvented cylinders, BoilerMate BP does not require expensive safety controls or the need to plumb temperature and pressure relief pipework to outside. External expansion vessels are not required and wiring is the same as any traditional Y, S or W plan system. BoilerMate BP thermal stores do not require any annual maintenance.

The BoilerMate BP is supplied without any system kit, which can be purchased as optional extras or be provided by the installer. The base unit is suitable for either open vented or sealed heating systems with the appropriate system kit.

The safety of a traditional system; BS6700: 1997 states that with unvented cylinders, the “maintenance and periodic easing of temperature relief valves is particularly important”. This is a landlord’s responsibility in tenanted properties and annual checks must be carried out by a CITB trained person or installer, having G3 approval. As BoilerMate BP is vented and therefore inherently safe, there is no requirement for a safety discharge, and it is not subject to Building Control Regulations – thus simplifying installation and system maintenance enormously for the landlords or homeowners.

BoilerMate BP for use with gas or oil boilers and renewable energy; BoilerMate BP is a mains pressure vented hot water thermal store suitable for open vented and sealed heating systems. The unit can be fitted with a conventional ‘S’ plan, ‘Y’ plan or a control system of your choice, and the controls can be plumbed inside the appliance giving a clean finish within the airing cupboard.

• Header tank can be sited remotely.
• Insulated in high performance metal cased foam.

How the BoilerMate BP works; The BoilerMate BP thermal storage system is supplied with primary water from the boiler which heats the store via a primary coil. Secondary water flows directly from the cold mains into a secondary coil where it is heated by the store before being delivered to the taps.

Thermally advanced; It is not widely appreciated that uncased foam insulated cylinders can lose up to 40% of their insulation value within weeks of manufacture and can emit dangerous smoke if involved in a fire and therefore the BoilerMate BP has been designed with an outer metal case. As with all Gledhill cylinders there is no release of ozone depleting substances or harmful emissions.

Cold and hot water distribution design – all models; BoilerMate BP models are designed to be fed directly from the mains. They fulfil the requirements of Water Regulations and therefore do not require a check valve to be fitted to the supply pipe. The performance of the BoilerMate BP is directly related to the adequacy of the cold supply to the dwelling. This must be capable of providing for those services which could be required simultaneously and the maximum demand should be calculated. BoilerMate BP will operate at dynamic pressures as low as 1.5 bar (at the appliance) which must be available when local demand is at its maximum, but the preferred range is between 2 and 3.5 bar. As a general guideline, although a 15mm external service may be sufficient for the smaller dwelling with one bathroom, a 22mm service is preferred (25mm MDPE) and should be the minimum for larger dwellings.
