Beyond the Boiler: Unvented Hot Water Cylinders in Southampton

When most Southampton homeowners think about their heating system, they focus primarily on their boiler. However, there’s another crucial component that can dramatically improve your hot water experience – the unvented hot water cylinder. As specialists in comprehensive boiler services in Southampton and complete heating solutions, we’ve helped countless local families transform their hot water systems with these innovative cylinders that deliver mains pressure hot water throughout the home.   What Are Unvented Hot Water Cylinders? Unvented hot water cylinders represent a significant advancement in domestic hot water technology. Unlike traditional vented cylinders that rely on gravity feed from a cold water tank in the loft, unvented systems connect directly to the mains water supply. This direct connection eliminates the need for cold water storage tanks whilst delivering hot water at mains pressure to every tap and shower in your Southampton home. The system works by heating water within an insulated cylinder using either an internal electric immersion heater or an external heat source like your boiler. Advanced safety controls, including temperature and pressure relief valves, ensure safe operation without requiring the open vent pipe that traditional systems need.   Advantages of Unvented Systems for Southampton Homes Southampton’s diverse housing stock –

How to Choose the Right Boiler Size for Your Home

Are you considering a new boiler installation in Winchester? Selecting the right size boiler is crucial for maintaining a warm, comfortable home whilst keeping your energy bills in check. At LW Gas, we’ve installed countless boilers across Hampshire, and we’ve found that many homeowners aren’t aware of how important proper boiler sizing really is. Why Boiler Size Matters Choosing the incorrect boiler size can lead to a host of problems. A boiler that’s too small will struggle to heat your home effectively, working overtime and potentially wearing out faster. On the other hand, an oversized boiler will waste energy through unnecessary cycling (turning on and off), costing you more money than necessary and potentially shortening the unit’s lifespan. Factors That Determine the Right Boiler Size Property Size and Type The square footage of your home is the most obvious factor in determining boiler size. A small flat will naturally require less heating capacity than a large detached house. However, there’s more to consider than just the floor area: Number of bedrooms and bathrooms: Each additional room that needs heating increases your requirements Ceiling height: Higher ceilings mean more volume to heat Property age: Older properties often have poorer insulation and
