You can use an electric shower regardless of the type of boiler or heating system you have, because it runs separately. Another great bonus of this is that you will still have access to hot water if your boiler breaks down . Battery-powered camping showers are popular because they are highly portable. They often weigh less than 2lbs (0.9kg) and are fairly compact in size. Plus, the pumps on these models often have built-in filters you so you only have to bathe in clean water. TIP: If changing to a combi boiler or fitting an unvented high pressure cylinder , power showers or shower pumps simply won’t work . The shower will have to be replaced or the shower pump removed. Option 3: Mixer valve showerThe rule of thumb is that any showerwhose shower valve is compatible with a combi can be used with one. There are some other things to look out for too: If you are unsure how to fix something, ring the phone number on your boiler, or talk to a qualified professional. In conclusion… Take note: A power shower may cause your unit to become over-pressurised, which can be dangerous. Our recommendations are based around making shower time as safe and pleasurable as possible. What’s the Best Shower to Use With A Combi Boiler? The main takeaways when considering the benefits of combi boilers versus alternatives are as follows:

The number of people that can use the same camping shower comes down to two factors: flow rate and water capacity. These two factors will determine how long you can use a portable shower for and, subsequently, how many people can use the same one. The 11L model can provide up to 7 minutes of continuous water pressure. It has a 7-foot neoprene sprayer hose that can be slung over a tree for showering. Or, you can use the hose to rinse off dirty gear after a long day outside. In fact, someone over at the Screwfix support forums had this to say: "If the hot water flow rate of your boiler is enough to meet the requirements of the mixer then I cannot think of a reason not to use a mixer."This is because the valve is able to control for any variations that may occur in the temperature of the water, meaning you get a consistent and perfectly heated stream of water to shower under.If you only have one bathroom or shower room, I would have a high pressure mixer valve shower with a combi boiler . Most good boilers are very reliable with up to a 10-year guarantee . So you are more or less guaranteed you will always have hot water. Conclusion This can also happen when the boiler automatically turns off the hot water once a certain temperature is reached. Investigate the preset temperature valve to determine if this is the case. Usually these are set around 43 degrees celsius to prevent scalding.
