Boilers & Central Heating
How much does a new boiler cost in Bournemouth or Poole?
The cost of a new boiler depends on the type of boiler, the size of your property, your hot water requirements and the complexity of the installation. Replacing an existing boiler in the same location may be more straightforward than changing the system or relocating equipment. A property-specific quotation is the best way to establish the cost.
Should I repair my boiler or replace it?
This depends on the boiler's age, condition, reliability and the cost of repairs. If your boiler regularly breaks down, replacement parts are difficult to obtain or repairs are becoming expensive, a new installation may be worth considering. A qualified heating engineer can assess the existing system and explain your options.
How often should a gas boiler be serviced?
Most manufacturers recommend having a gas boiler serviced annually. Regular servicing helps identify potential problems, maintain safe operation and support efficient performance. It may also be required to maintain the manufacturer's warranty.
Why is my boiler losing pressure?
Boiler pressure can fall for several reasons, including leaks, problems with the expansion vessel or issues with other heating system components. If you're repeatedly topping up the pressure, it's important to have the cause investigated rather than continually repressurising the system.
Why are some radiators hot while others stay cold?
Uneven radiator temperatures can be caused by trapped air, balancing issues, sludge build-up or circulation problems. If a radiator is cold at the top, trapped air may be responsible. Cold areas at the bottom can indicate a build-up of deposits. Persistent problems should be assessed by a heating engineer.
Why does my boiler keep switching itself off?
A boiler may repeatedly shut down because of low pressure, overheating, circulation problems or a fault with an internal component. Check the manufacturer's instructions for any displayed fault code, but avoid attempting internal repairs. If the problem continues, arrange a professional inspection.
Is it worth replacing an old boiler with a more efficient model?
Replacing an older, inefficient boiler can improve heating performance and may reduce energy consumption, depending on the existing system and how the property is used. The potential benefits should be considered alongside installation costs, insulation and the overall condition of your heating system.
Can a heating engineer help if my radiators aren't getting hot?
Yes. Radiators that aren't heating properly may indicate issues with the boiler, pump, valves, system pressure or circulation. A heating engineer can investigate the cause and recommend suitable repairs.
Hot Water & General Plumbing
Why do I have no hot water but my heating still works?
If your central heating is working but you have no hot water, the cause could involve a diverter valve, thermostat, hot water cylinder or another system component. The exact cause depends on the type of boiler and hot water system installed. A professional inspection can identify the problem.
What's the difference between a vented and unvented hot water cylinder?
A vented hot water cylinder typically receives its water supply from a cold water storage tank, often located in the loft. An unvented cylinder is supplied directly from the mains and stores hot water under pressure. The best option depends on your property's water pressure, plumbing layout and hot water requirements.
Can I replace my old hot water cylinder with an unvented system?
Many properties can be upgraded to an unvented hot water cylinder, but suitability depends on the incoming mains water supply, available space and installation requirements. Unvented systems must be installed by appropriately qualified professionals.
Why does my hot water run out so quickly?
Running out of hot water can be caused by an undersized cylinder, thermostat problems, heating faults or increased household demand. The right solution depends on your current system and how much hot water your household uses.
Why is my water pressure low upstairs?
Low water pressure upstairs can be linked to the property's plumbing arrangement, mains supply, restrictions in pipework or simultaneous water use. Some older gravity-fed systems naturally provide lower pressure than mains-fed alternatives. Identifying the type of system is the first step.
When should I call a plumber for a leaking pipe?
A leaking pipe should be addressed promptly, particularly if water is reaching electrical fittings, ceilings or structural areas. If safe, turn off the water supply to limit damage and contact a plumber. Even small leaks can cause significant damage if left unresolved.
Home Air Conditioning & Cooling
How much does it cost to install air conditioning in a house in Dorset?
Domestic air conditioning installation costs depend on the number of rooms, system capacity, equipment selected and installation complexity. A single-room system will generally cost less than a multi-room installation. A quotation based on your property's layout and cooling requirements will provide a more accurate figure.
Can you install air conditioning in a bedroom?
Yes. Wall-mounted air conditioning systems are commonly used in bedrooms to maintain comfortable sleeping temperatures during warmer weather. Correct sizing and careful positioning are important to manage noise, airflow and comfort.
Is air conditioning worth installing in a UK home?
Air conditioning can be a worthwhile investment for homes that become uncomfortably warm, particularly bedrooms, loft conversions, conservatories and south-facing rooms. Many modern systems also provide heating, allowing homeowners to use them throughout the year.
Can air conditioning heat my home in winter?
Yes. Many modern air conditioning systems operate as air-to-air heat pumps, providing both heating and cooling. Their suitability as a primary or supplementary heating solution depends on the property, insulation, system design and individual heating requirements.
How much electricity does home air conditioning use?
Electricity consumption depends on the system's efficiency, capacity, temperature settings and how long it operates. Modern inverter-driven air conditioning systems can adjust their output to maintain the selected temperature rather than continually operating at full capacity. Running costs also depend on your electricity tariff.
Can I install air conditioning in just one room?
Yes. A single-split air conditioning system can provide heating and cooling for an individual room, such as a bedroom, living room or home office. Multi-split systems may be suitable where several rooms require temperature control.
Do I need planning permission for air conditioning in my home?
Some domestic air conditioning installations in England may qualify as permitted development, subject to conditions. Requirements can vary depending on the equipment, property type, external unit position and whether the property is listed or in a conservation area. Check with your local planning authority before installation.
Is air conditioning noisy?
Modern domestic air conditioning systems are generally designed for quiet operation, particularly indoor units with dedicated low-noise or sleep settings. Noise levels vary by model, installation and operating conditions, so it's worth discussing this when selecting a system.
Does home air conditioning need servicing?
Yes. Regular cleaning and maintenance help maintain airflow, efficiency and reliability. Filters may need cleaning more frequently depending on usage, while professional servicing requirements depend on the equipment and manufacturer's recommendations.
Can air conditioning help cool a loft conversion?
Yes. Loft conversions can become particularly warm because of their position beneath the roof and exposure to sunlight. Air conditioning can provide effective cooling, although correct system sizing should take account of insulation, glazing and room dimensions.
Choosing the Right Heating or Cooling System
What should I consider before replacing my heating system?
Consider your property's size, insulation, existing pipework, hot water demand, installation budget and long-term running costs. A heating engineer can help assess the current system and explain which options may be suitable.
What should I ask before getting air conditioning installed?
Ask about system sizing, equipment efficiency, installation location, noise levels, running costs, maintenance requirements and warranty cover. A suitable system should be selected for your property's specific heating and cooling needs rather than simply choosing equipment based on price.
How do I choose a heating engineer in Dorset?
Look for relevant qualifications and registrations, experience with the type of heating system you have, clear quotations and genuine customer feedback. Gas work must be carried out by an appropriately registered Gas Safe engineer, while oil heating and unvented hot water work have their own competency requirements.
Can I get a quote for heating, plumbing or air conditioning work?
Yes. Contact RJ Oliver Heating & Cooling Services with details of your property and the work you're considering. Whether you need help with an existing system or are planning a new installation, we can discuss your requirements and the next steps.
