Is your boiler making strange noises or failing to provide adequate heating? As experienced boiler repair specialists in Southampton and across Hampshire, we’ve seen it all when it comes to boiler issues. While some problems require professional assistance, others have simple fixes you can try yourself. Here are the 10 most common boiler problems we encounter and what you can do about them. 1. No Hot Water or Heating This is perhaps the most common complaint we hear from homeowners. Possible causes: Thermostat issues Low water pressure Broken diaphragm or airlock Faulty motorised valve What you can try: Check your thermostat settings first. Ensure it’s switched on, set to the correct mode, and the temperature is high enough to trigger heating. If your pressure gauge shows below 1 bar, you might need to repressurise your system following your boiler manual’s instructions. When to call a professional: If checking your thermostat and pressure doesn’t resolve the issue, it’s time to call in a Gas Safe registered engineer. 2. Boiler Leaking or Dripping Water leaking from your boiler should never be ignored as it can cause damage to your home and the boiler itself. Possible causes: Broken internal components (pump, pressure valve,

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

When it comes to choosing a new boiler for your Hampshire home, comparing Worcester Bosch vs Ideal boilers is often the first step many of our customers take.

Is your boiler trying to tell you something? If you notice unusual behaviour from your heating system, it could be a sign that your boiler needs some TLC and maybe an annual service is required. As Hampshire’s trusted heating experts since 2003, we’ve helped countless homeowners recognise when their boilers need professional care before small issues become major headaches. 1. Strange Noises Banging, whistling, or gurgling sounds aren’t normal for a well-functioning boiler. These noises often indicate air in the system, pump problems, or potentially harmful limescale build up. If your once-quiet boiler has become a noisy nuisance, call the professionals. 2. Increasing Energy Bills Have your heating bills suddenly shot up without a corresponding increase in usage? An inefficient boiler works harder to produce the same amount of heat, consuming more fuel and inflating your energy costs. Our heating engineers can identify efficiency issues and often restore optimal performance with a proper maintenance visit. 3. Yellow Flame Instead of Blue A healthy gas boiler should have a steady blue flame. If you notice yours burning yellow, this could indicate incomplete combustion and potentially dangerous carbon monoxide production. This requires immediate professional attention – don’t delay calling a Gas Safe

Maintaining an LPG (Liquefied Petroleum Gas) boiler is crucial to ensure it operates efficiently and safely, especially in areas like Stockbridge. At LW Gas Ltd, we provide comprehensive maintenance services to keep your boiler in top condition. Here’s what you need to know about maintaining your LPG boiler. Annual Servicing An annual service is essential for the optimal performance of your LPG boiler. This involves a thorough inspection and cleaning of key components such as the burner, heat exchanger, and flue. Regular servicing helps identify and rectify potential issues before they become major problems, ensuring your boiler runs efficiently and safely. Check for Leaks LPG boilers require regular checks for leaks in the gas line and the boiler itself. Leaks can be dangerous and lead to inefficiency. During a service, our qualified technicians at LW Gas Ltd will inspect for any signs of leakage and ensure all connections are secure. Inspecting the Flame The flame in your LPG boiler should be clear and blue. A yellow or orange flame can indicate incomplete combustion, which can be dangerous and lead to increased carbon monoxide production. Regular inspections by our professionals ensure that the flame is burning correctly. Ventilation and Flue Checks

Selecting the right gas boiler for your home is a crucial decision, particularly in areas like Owlesbury, where reliable heating is essential. At LW Gas Ltd, we understand the importance of making an informed choice. Here’s a guide to help you navigate the options. Understanding Your Heating Needs First, assess your home’s heating requirements. Consider the size of your property, the number of radiators, and your hot water needs. Larger homes with multiple bathrooms will require a more powerful boiler compared to smaller properties. Types of Gas Boilers Combi Boilers: These are compact and efficient, providing both heating and hot water on demand without the need for a separate tank. Ideal for smaller homes or flats, combi boilers save space and can be more cost-effective. System Boilers: System boilers require a separate hot water storage cylinder but no expansion tank. They are suitable for larger homes with higher hot water demands, as they can supply hot water to multiple outlets simultaneously. Conventional Boilers: Also known as regular or heat-only boilers, these require both a hot water cylinder and a cold water storage tank. They are ideal for homes with traditional heating systems and high hot water usage, providing a steady
