While we acknowledge that the manual fill of the header tank can be inconvenient for some homeowners, this feature has important safety implications since it significantly reduces the potential for damage to the property and potential injury to residents in apartments below.

You can install a ball cock with automatic topping up on the system. However, in the event of a leak or ball valve failure, systems which automatically fill themselves up will continue to do so indefinitely until the problem is resolved. Such issues have been responsible for causing massive damage to property and the implications of leaks within apartment developments can be extremely serious.

By contrast, the inability of the PulsaCoil unit to top itself up means that in the event of a significant leak, the only water that can be lost is the water held in the cylinder at that time.

If you are unable to easily see the water level in the header tank, then we can install a sight glass to many types of header tanks which makes checking water levels quicker and easier. The installation of the sight glass enables you to see the required level exactly, simply by opening your airing cupboard door.

We will automatically check water levels when attending to conduct an annual healthcheck with our Platinum package.

The header tank should be filled with clean cold water approximately halfway up the tank. It is important not to overfill the tank as this can create problems.

We advise that the header tank water level is checked every three months. You can help reduce the amount of water lost during operation by ensuring the lid of the header tank is securely replaced.

Some system types (-such as unvented cylinders) require a check every year to maintain warranty cover and to ensure your safety. However, the inherent safety of appliances like the open vented PulsaCoil mean that no such annual service is required for many other systems.

We have designed our boiler and home cover packages to reflect the needs of these different products, but our office team will be more than happy to guide you if you have any further questions.

Although an annual inspection is not a necessity for all Gledhill appliances, we do offer a yearly health check option for almost all products. As an appliance ages, more regular maintenance is required and the likelihood of a breakdown increases. An annual check allows our engineer to assess that a boiler or system is functioning correctly and hopefully address any developing problem before it results in an unscheduled breakdown, reducing the risk of a ‘no hot water’ or ‘no heating’ situation and the resulting upset and frustration caused to the homeowner.

We offer a full range of annual maintenance agreements which provide the most cost effective and easy way of looking after your Gledhill appliance. Our directly employed team of experts will ensure you get the help you need when the unexpected happens.
