Worcester Heatslave 25/32 Oil Combi

The Worcester Heatslave 25/32 oil combi boiler is the most powerful model in the Heatslave II combi boiler range. It is designed to heat homes with three or four bedrooms and up to two bathrooms and is the most popular oil combi boiler on the market. Although most combi boilers run on gas, there are millions of UK homes without access to the main supply, making oil an alternative method of heating those properties. It is also possible to opt for an oil combi like the Worcester Bosch Greenstar Heatslave II 25/32 even if your home does receive natural gas.

At Clever Energy Boilers, we recommend Worcester Bosch products to our customers. This is to do with the fantastic reputation the company has with customers and industry professionals alike, the quality of the boilers they produce and their reliability too. The Worcester Heatslave combi boiler range has helped contribute to Worcester Bosch being named best boiler brand by Which? Magazine for ten years in a row. This poll is compiled by talking to trusted gas fitters, who praise Worcester Bosch for creating easy to install, service and repair boilers, and customers too.

Worcester Bosch Greenstar Heatslave II 25/32 Oil Combi Boiler Features

Here are some of the stand out Worcester Bosch Greenstar Heatslave II 25/32 oil combi boiler features:

  • Designed to look sleek, with concealed controls
  • Save energy by using eco hot water mode
  • Dimensions of the boiler allow it to fit under a standard kitchen counter for convenience
  • Prevent wasted energy with precision controls
  • Compatible with water from green sources
  • Compatible with smart controls

Many of us look for a combi boiler that works with smart controls nowadays, and the Worcester Heatslave 25/32 delivers on that score. If you use the Worcester 25/32 Heatslave with Worcester Bosch’s EasyControl system, not only do you have the convenience of adjusting your central heating and hot water wherever you have internet access, you also gain even more efficiency from your boiler. This saves you money on your heating bills and is better for the environment too. The precision controls of the Worcester Heatslave 25/32 mean that you don’t waste energy heating your home any more than you need too.

Design is key with the Worcester Greenstar Heatslave 25/32 combi oil boiler. If you want the boiler on show, it looks great and features concealed controls to maintain a sleek image that fits into any kitchen, bathroom or utility room. However, if you would prefer to keep it out of sight, the Worcester Heatslave 25/32 is just the right size to fit underneath a standard kitchen worktop. You could fit it within a cupboard and conceal it if you prefer.

If you heat water using green methods such as solar panels or wood fires, you can use that water with the Worcester Greenstar Heatslave II 25/32 combination boiler for greater efficiency too.

Cost of a Worcester Greenstar Heatslave 25/32

clever energy boilers teamThe cost of a Worcester Greenstar Heatslave 25/32 is dependent on the amount of work needed to install the device and the additional items you buy with it. To find an exact figure, book in a free, no obligation home survey from Clever Energy Boilers. We will send an experienced boiler expert to your home, who will assess your needs and provide you with a fixed quote for the complete job.

During their visit, they look to make sure that the Worcester Heatslave 25/32 oil combi boiler is the correct choice for your home. They will check it is powerful enough to heat all of your radiators and to provide adequate hot water for your family’s needs. However, they will also ensure that it isn’t over powered for your requirements, as that would mean that you would use more energy than you need to run the boiler and, therefore, spend more on your fuel bills than is necessary.

If you are swapping an oil combi boiler for a new Worcester Greenstar Heatslave II in the same location in your property, that would be a fairly straightforward job. However, if you were changing from a gas boiler or a system boiler, that would entail more work and lift the cost of installing the new boiler. Similarly, if you needed to move the position of the boiler, from a kitchen to a bathroom for example, the resulting work needed to reposition the pipework would add to the cost of a Worcester Greenstar Heatslave 25/32.

If you haven’t had an oil combi boiler before, you will need an oil tank to store your fuel. You might also want to add smart controls to your new boiler, for ease of use and convenience.

The home survey takes all of this into account and our staff member will leave you with the exact cost of carrying out the installation. This is fixed so that you can take time to consider it, and you can ask any questions you need to our customer care team on 0330 055 2210.

The Worcester Heatslave Range

Things You Need to Know Before Buying a New Boiler If the home survey reveals that a Worcester Heatslave 25/32 is too powerful for your home, with its 32kW central heating output and 22 litres per minute hot water flow rate, there are two smaller models in the range to pick from. The Worcester Heatslave 18/25 and Worcester Heatslave 12/18 come with the same range of innovative features, but with lower outputs. This means that you can ensure you find an oil combi boiler to save you the maximum amount of money on your home energy bills, whilst also being mindful of the environment.

If you want to make room in your home, you could opt for the Worcester Greenstar Heatslave II external oil combi boiler instead of the usual internal version. This boiler sits outside your home, encased in a robust protective shell to keep the elements at bay. There are external versions of all of the different sized boilers in the Worcester Heatslave range, so that option is available no matter the size of your home.

You might find that your hot water demands are too great for a combi boiler. In which case, Worcester Bosch provides oil system boilers. Take a look at the Danesmoor range to find out more about this option.
