Hot Water Cylinder Installation
Professional Hot Water Cylinder Installation in Marlow
Installing or upgrading a hot water cylinder is a smart investment for any Marlow home. At Jericos, we supply and fit a full range of high-quality cylinders — from traditional vented (gravity) models to modern unvented (pressurised) cylinders, commonly known as Megaflo.
Unvented cylinders are usually made from stainless steel and connect directly to the mains water supply for powerful pressure without a cold water tank in the loft. Vented cylinders are the older style, typically made from copper, and rely on a feed and expansion (F&E) tank in the loft for gravity-fed water.
All cylinders can usually be run from gas boilers, Air Source Heat Pumps (ASHP), or electric boilers. Our G3 qualified engineers assess your property’s needs, boiler compatibility, and hot water demand before recommending the perfect solution. Indirect cylinders work seamlessly with your primary heating system, while direct models suit specific requirements. We ensure correct sizing (typically 150–300 litres for family homes), proper insulation for energy efficiency, and full safety features including expansion vessels, pressure relief valves, and temperature controls.
Benefits of a new cylinder installation include:
- Stronger water pressure for powerful showers and faster-filling baths
- Improved energy efficiency and lower fuel bills (especially when combined with a modern gas boiler)
- Enhanced reliability and reduced risk of leaks or failures
- Full Building Regulations compliance and certification
We handle all aspects of the job — from removing your old unit and disposing of it responsibly to commissioning the new system and providing clear operating instructions. All installations come with manufacturer warranties and our own workmanship guarantee.
As local experts based in Marlow, we understand the typical plumbing and heating setups in Bucks properties, including older homes that often benefit from upgrading from vented to unvented systems. Let us help you enjoy reliable, plentiful hot water every day.
Hot Water Cylinder Repair
Fast Hot Water Cylinder Repair Services in Buckinghamshire
A faulty hot water cylinder can quickly disrupt your daily routine. Common issues we repair in Marlow homes include leaks from corroded tanks or joints, faulty immersion heaters, failed thermostats, pressure relief valve problems, and other performance issues.
Our experienced engineers diagnose problems quickly and provide cost-effective repair solutions. Many issues, such as a leaking immersion heater or stuck temperature valve, can be fixed on the same day without a full replacement. We specialise in repairs linked to your gas boiler system — ensuring the primary heating circuit and cylinder work together safely and efficiently.
Signs your cylinder needs attention:
- No hot water or lukewarm supply
- Strange noises (gurgling, banging, or rumbling)
- Water leaks around the base or pipe connections
- Discoloured or smelly hot water
- Reduced pressure at taps and showers
We always provide honest advice — repairing where possible to save you money, or recommending replacement when a repair would only offer short-term relief. All unvented cylinder work is carried out by our G3 qualified engineers in full compliance with Building Regulations.
Hot Water Cylinder Servicing
Regular servicing is the best way to keep your hot water cylinder performing efficiently and safely for years to come. Jericos offers thorough servicing packages tailored to both vented (gravity) and unvented (pressurised / Megaflo) cylinders.
During a service we:
- Inspect and test all safety devices (essential for unvented systems)
- Check temperature controls and pressure levels
- Advise on any efficiency improvements, especially when integrated with your gas boiler
Servicing helps prevent breakdowns, extends the life of your cylinder, maintains energy efficiency, and ensures full compliance with regulations. Many homeowners combine cylinder servicing with their annual boiler service for convenience and cost savings.
Our local G3 qualified engineers serve Marlow, High Wycombe, and surrounding Buckinghamshire postcodes with flexible appointments to suit your schedule.
