Professional Thermal Stores: 
Efficient Hot Water Solution in Kent

Modernizing your home's heating system can reduce utility costs and improve comfort. A thermal store represents a significant technological leap over traditional cylinders. It acts as a high-efficiency heat battery, managing and storing thermal energy to provide mains-pressure hot water and space heating on demand.

At AQUAHEAT, we specialize in thermal store installation in Kent. Our engineers design tailored heating solutions that integrate multiple energy sources into one dependable system.

How Does a Thermal Store Work?

A thermal store reverses the traditional approach to domestic hot water. In a standard system, you store "secondary" water (tap water). In a thermal store, the cylinder contains "primary" heating water that remains in the tank.

When you turn on a tap, cold mains water flows through a high-efficiency internal coil or a Plate Heat Exchanger (PHE). Heat transfers immediately from the stored primary water to the fresh mains water, ensuring high-pressure hot water without complex unvented systems or discharge pipework..

Benefits of Choosing Thermal Stores for Your Kent Property

AQUAHEAT’s Kent heating services prioritize longevity and versatility.
 Thermal stores offer several advantages over traditional unvented cylinders:

Multi-Fuel Integration & Stove Heating

The main strength of a thermal store is its ability to act as a central point for different heat sources. We can link your thermal store to:

Gas or Electric Boilers:

A dependable foundation for your needs.

Solar Thermal or PV Panels

Using renewable energy to heat your water at no expense.

Stove Heating

Use a wood burner or solid fuel stove to heat the entire house with radiators, ensuring no heat from your fire is wasted.

Cost-Efficiency and Easy Maintenance

Unlike unvented cylinders requiring annual G3 safety inspections, thermal stores are typically open-vented. This reduces maintenance costs over time.

AQUAHEAT recommends professional checks on your thermal store for optimal performance.

• System Health: We verify that pumps, thermostats, and safety valves operate effectively.
• Corrosion Protection: We ensure the system's inhibitor levels are correct to protect your investment.
• Hard Water Care: In Kent’s hard water areas, we can descale or service the Plate Heat Exchanger to ensure optimal flow rates.

Superior Heating. Local Expertise. 

AQUAHEAT offers energy-efficient hot water solutions tailored to the South East.

Our goal is to deliver reliable warmth, from rural "off-grid" cottages in Kent to modern apartments in Ashford and Maidstone.

• Technical Authority: Many installers avoid thermal stores due to the specialized knowledge required for multi-fuel integration. However, AQUAHEAT embrace them as the standard of modern heating.

• Local Expertise: We’re a local Kent business, knowledgeable about the county’s water pressure and infrastructure challenges.

Frequently Asked Questions

Do thermal stores provide mains pressure hot water?

Yes, they deliver high-performance, mains-pressure hot water to multiple outlets simultaneously without a noisy pump.

How does AQUAHEAT improve energy efficiency?

We design systems that capture energy when it’s most cost-effective (like solar gain or off-peak electricity) and store it for peak demand times.

What is a thermal store’s lifespan?

When installed by specialists like AQUAHEAT, these systems are durable and often outlast traditional boilers due to their robust, low-pressure design.

Can I add solar panels later?

Yes. We can install "solar-ready" thermal stores, allowing you to upgrade to renewable energy when your budget allows.

Do you cover my area?

We provide coverage across Kent, including Ashford, Hythe, New Romney, Chilham and nearby areas.

Can I heat my radiators with a stove?

Yes. By connecting a boiler-stove to a thermal store, the heat from your fire is stored in the tank and pumped to your radiators or underfloor heating as needed, even after the fire has gone out.

Is it cheaper to run a stove than a gas boiler?

Yes, especially with a sustainable wood supply. Using a thermal store to distribute stove heat throughout the house reduces reliance on expensive mains gas or electric.

From the initial call to Aquaheat when the boiler had failed to engineer calling and trying to repair then the boiler being replaced the journey was second to none. Two engineers (Ryan and Owen) replaced the boiler and radiator. Exceptional professionalism from start to finish. Dust sheets were layed and overshoes worn and on completion everything was left clean and tidy. The operation of the boiler was fully explained. There was excellent communication via email with quotes and timescales. I would highly recommend Aquaheat for price and professionalism throughout.
