Mains pressure hot water from an open vented thermal store

Whilst highly desirable, mains pressure hot water has historically brought with it the dangers associated with unvented (pressurised) cylinders - EXPLOSION! Until the advent of the Boilermate that is!

With the simple yet clever addition of a mains-pressure heat exchanger a normal gravity pressure open-vented vessel can be transformed to provide mains pressure hot water with performance to match any other system.

This is basically the principle the Boilermate employs. High performance mains pressure hot water without any of the baggage unvented systems bring with them - G3 Building Regs, Specialist Installers, Risk of explosion, pressure relief issues and pipework etc.

Boilermate has been around for quite some time. The system has been widely used throughout the UK within the 'new-build' market and by discerning householders how have recognised the superior performance and advantages of the system over others - previous generations include Boilermate 2000 and Boilermate A Class ranges.

If you are looking to upgrade your system (which can be done with consummate ease) or you wish to replace an earlier version with the new Boilermate BP you might like to call our office to learn more.

As a replacement

For those wishing to replace earlier versions of the Boilermate and Systemate please be advised that while the function remains similar the new BP model differs internally. Earlier models contained various auxiliary components (pumps, circuit boards, timers etc). The design of the new Boilermate BP has made the function and therefore the need for certain internal components on the earlier model redundant. The new unit will however need a couple of items added externally in order to function - namely a circulating pump and programmer.

It must also be mentioned that the function of the new Boilermate BP is to produce mains pressure hot water only - unlike some earlier models of Boilermate that also managed domestic heating requirements. When replacing some earlier models minor adaptation of pipework may be necessary to facilitate a Y or S plan installation.

A 3kW immersion heater and a choice of scale inhibitors is available. These however are options and must be stated and ordered at time of purchase.

The removal of certain internal components has made the Boilermate visually and operationally less intimidating to plumbers unfamiliar with the product and/or the principles of Thermal Storage. It has also reduced the purchase cost substantially!

Boilermate by Gledhill

Boilermate BP - Mains hot water from a Thermal store

The BoilerMate BP is an open vented thermal store. Although it produces hot water at mains pressure it has no need for pressure relief or safety equipment as by virtue of its open vented status the unit is totally safe.

Reflecting not only in the cost of purchase and installation, more importantly this makes the Boilermate a wise choice for the safety conscious home owner and landlord.

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.

Boilermate is a superb and simple way to upgrade an existing traditional gravity hot water system to mains pressure.

Mains pressure hot water
BoilerMate BP thermal store provides:
• 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.

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.


Below are a couple of typical configuration schematics for the Boilermate BP model.

Boilermate BP technical information

Gledhill Boilermate Techical Specifications

 

Notes:
1. The appliance is supplied on a 100mm high installation base and comes complete with a separate top up cistern. This can be installed with or without an overflow/warning pipe as required.
2. An allowance for the top up cistern and the 100mm installation base are both included in the minimum cupboard dimensions.

Please Note: Where the mains water hardness exceeds 200ppm provision should be made to treat the feed water to reduce the rate of accumulation of lime scale. The optional factory fitted in-line scale inhibitor should be specified at the time of order for hardness levels between 200 and 300 ppm (mg/l). Where the water is very hard ie 300ppm (mg/l) and above the optional polyphosphate type scale inhibitor should be specified at the time of order.

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.

Water treatment
The Domestic Heating Compliance Guide published in May 2006 requires a water treatment device to be fitted where the hardness is greater than 200ppm. Full details are given in the Design & Installation manual supplied with all BoilerMate BP units.

Optional plastic pipework – all models
This appliance is suitable for use with plastic pipework as long as the material is recommended for the purpose by the manufacturer and is installed fully in accordance with
their recommendations.
