Choosing the right Sanicondens pump mainly depends on what equipment it is connected to, where the pump can be fitted and how far the condensate needs to travel.
The current Sanicondens range includes discreet pumps for air-conditioning installations, larger tank units for boilers and mixed-use equipment, and a model with integrated condensate neutralisation. This guide compares the full UK range and explains which pump suits each application, considering pumping height, pipe length, noise, available space and maintenance access.

What Is a Sanicondens Pump?
Condensate is the water produced by equipment such as air-conditioning systems, condensing boilers, refrigeration units and dehumidifiers. Where possible, this water can drain away naturally through pipework using gravity.
A Sanicondens pump is used when the condensate cannot reach a suitable drain on its own. The pump collects the water and automatically discharges it through small-diameter pipework to a drain located higher up or further away.
Different appliances produce different volumes and types of condensate. Air-conditioning systems generally need a compact pump suited to the expected water flow, while boiler condensate can be acidic and may also require neutralisation. This is why the correct model should be chosen for the appliance and installation rather than simply by pump size.
For a closer look at where this water comes from and how it is normally removed, read our guide to air-conditioning installation and condensate drainage.
Best Sanicondens Pumps for Air Conditioning
For most wall-mounted air-conditioning units, choosing the right pump is mainly about where it can be fitted and whether it will remain visible. The Clim Mini, Clim Pack and Clim Deco are designed for smaller air-conditioning installations, while the Clim Maxi is intended for ceiling cassettes and equipment producing larger amounts of condensate.
Sanicondens Clim Mini
Best for: hiding the pump from view
The Sanicondens Clim Mini is the best starting point for a typical wall-mounted air-conditioning unit where the pump can be concealed. Its compact design allows it to sit close to the indoor unit without becoming a noticeable part of the room.
Choose the Clim Mini when appearance matters and there is a suitable accessible space for the pump and sensor. It is designed specifically for air-conditioning condensate and uses narrow discharge pipework.
Sanicondens Clim Pack
Best for: a neat installation when the pipework cannot be hidden
The Clim Pack uses the same compact pump as the Clim Mini but includes trimmable trunking. This provides a cleaner finish where the pump and pipe route need to sit visibly beside a wall-mounted air-conditioning unit.
It is not a more powerful alternative to the Clim Mini. The main difference is the supplied trunking and how neatly the finished installation can be presented.
Sanicondens Clim Deco
Best for: fitting the pump visibly beneath the air-conditioning unit
The Clim Deco is enclosed within a discreet casing designed to remain visible. It is useful where there is nowhere suitable to conceal a separate pump or where straightforward access is preferred.
It can be used with air-conditioning and refrigeration equipment and is intended to provide a more finished appearance than an exposed pump and pipe arrangement.
Sanicondens Clim Maxi
Best for: ceiling cassettes and larger cooling equipment
The Clim Maxi is designed for larger air-conditioning systems, ceiling cassettes, refrigerated display units and dehumidifiers. It is the more suitable option where the equipment may produce more condensate than a small wall-mounted unit.
The correct choice still depends on the expected condensate output and drainage route, so it should not be selected simply because it is the largest model in the range.
Best Sanicondens Pumps for Boilers and General Use
For boilers and other condensate-producing equipment, the best pump depends on the appliance, the available space and whether the acidic condensate needs to be neutralised.
The Deco+ is designed for smaller wall-mounted gas boilers. The Eco and Pro are broader general-purpose options that can also serve refrigeration, dehumidifiers and some air-conditioning systems. The Best Flat combines condensate pumping with built-in neutralisation.
Sanicondens Deco+
Best for: a compact wall-mounted gas boiler
The Sanicondens Deco+ is designed for gas boilers with an output of up to 25kW. Its small casing and quiet operation make it particularly suitable for kitchens, cupboards and other areas where space is limited.
It has a much smaller tank than the Eco or Pro, so it is intended as a discreet boiler solution rather than a general-purpose pump for larger equipment. It can pump condensate up to 6 metres vertically or 60 metres horizontally, subject to the installation requirements.
Sanicondens Eco
Best for: straightforward general-purpose condensate pumping
The Sanicondens Eco can collect condensate from gas or oil boilers, air-conditioning systems, refrigeration equipment and dehumidifiers. It has two inlets and a 2.2-litre tank, making it a flexible option where several types of equipment may need a larger collection pump.
Choose the Eco when you need a capable general-purpose unit but do not need built-in neutralisation. Saniflo recommends maximum pumping of up to 4.5 metres vertically or 50 metres horizontally with the required fall.
Sanicondens Pro
Best for: a complete general-purpose installation package
The Sanicondens Pro serves much the same range of equipment as the Eco, including gas and oil boilers, refrigeration systems, air-conditioning units and dehumidifiers.
The main reason to choose the Pro is the supplied installation equipment. It includes a non-return valve, flexible discharge pipe and a complete fitting kit, and it can be installed on the wall or floor.
Like the Eco, it has two inlets, a 2.2-litre tank and recommended pumping limits of up to 4.5 metres vertically or 50 metres horizontally. It is therefore not simply a larger Eco. It is the more complete packaged option.
Sanicondens Best Flat
Best for: floor-standing boilers and built-in condensate neutralisation
The Sanicondens Best Flat combines a condensate pump and neutralising system in one unit. The neutralising material helps reduce the acidity of boiler condensate before it enters the drainage system.
Its low inlet makes it particularly useful beside floor-standing boilers. It also has two inlets, a 3.5-litre tank, an alarm connection and a supplied non-return valve.
Choose the Best Flat when the low entry point or built-in neutralisation is the main requirement. Where neither is needed, the Eco or Pro may provide a simpler solution.
Do I Need a Condensate Neutraliser?
Condensate from a modern boiler can be acidic. Depending on the boiler, drainage materials and installation requirements, it may need to be treated before it enters the drainage system.
A condensate neutraliser contains granules that help reduce this acidity. It is important to understand that a neutraliser does not necessarily pump the water. It treats the condensate before it drains away or enters a separate condensate pump.
Saniflo offers two separate neutralisers:
- Sanineutral Mini: designed for gas boilers up to 25kW.
- Sanineutral: intended for larger boiler installations and can be positioned before a Sanicondens Eco or Pro.
Both work without their own pump. Where the condensate also needs to be lifted to a higher drain, a separate Sanicondens pump may still be required.
The Sanicondens Best Flat is different because it combines pumping and neutralisation in one unit. This makes it particularly useful for floor-standing boilers or installations where a single combined solution is preferable.
Frequently Asked Questions
Which Sanicondens pump is best for air conditioning?
For a typical wall-mounted air-conditioning unit, the choice is usually between the Clim Mini, Clim Pack and Clim Deco. Choose the Clim Mini when the pump can be hidden, the Clim Pack when surface trunking is required, and the Clim Deco when the pump will remain visible. Larger cassette systems may require the Clim Maxi.
What is the difference between the Sanicondens Eco and Pro?
Both are general-purpose condensate pumps with two inlets and a 2.2-litre tank. The Sanicondens Pro is supplied as a more complete installation package, including a non-return valve, flexible discharge pipe and fitting kit. The Sanicondens Eco is the more straightforward general-purpose option.
Is the Clim Pack more powerful than the Clim Mini?
No. The Clim Pack uses the same compact pump as the Clim Mini. Its main difference is the supplied, trimmable trunking, which provides a neater finish when the pump and pipework must remain visible on the wall.
Can one Sanicondens pump be used for any appliance?
No. Different Sanicondens pumps are designed for different appliances, condensate volumes and installation arrangements. The connected equipment, pumping height, pipe length, temperature, acidity and maintenance access should all be considered before a model is selected.
Does every boiler condensate pump need a neutraliser?
Not necessarily. Whether neutralisation is required depends on the boiler, the drainage materials and the installation instructions. A separate Sanineutral unit can be used where treatment is needed, or the Sanicondens Best Flat provides pumping and neutralisation within one unit.
What happens if a condensate pump stops working?
Condensate may back up, leak or activate an alarm where one is connected. Some installations may also stop the connected appliance to help prevent an overflow. A pump that is leaking, unusually noisy or running repeatedly should be checked before it fails completely.
Can I replace an old condensate pump with any current model?
Not automatically. The replacement must suit the connected appliance, condensate output, existing pipe sizes and drainage route. Check the model label and the surrounding installation before choosing a replacement.
