How to choose a water booster (hydrophore) for your home?

A water booster keeps the water pressure in your home constant: the pump starts and stops automatically as you use water. The right choice depends mainly on the water source (borehole, shallow well or mains), the required flow (number of taps) and the noise level.

A floor-standing booster (SCALA1, SCALA2, JP) is installed in a dry room and draws water from wells up to 8 m deep. If the water level is deeper or you want the pump inside the well, the submersible SBA booster is the right choice — silent and needing no dry installation space.

For a detached house with 3–6 taps, SCALA2 is the best choice, keeping the pressure perfectly constant even with several simultaneous users. A more affordable alternative is SCALA1 or the classic JP hydrophore; for a summer cottage or garden, JP is usually enough.

For an office or commercial building choose a quiet booster that handles simultaneous use — Grundfos SCALA2 suits a 5–20 person office for the kitchen, restrooms and other taps; a smaller office is fine with SCALA1.

To compare water boosters with other Grundfos solutions, see the Grundfos water boosters selection guide on our homepage, with price ranges and advice for every series.

Frequently asked questions

What is the best water booster for a detached house?+
For most detached houses the best choice is Grundfos SCALA2: it keeps the pressure constant even when several taps are open and is practically silent. On a tighter budget, SCALA1 offers the same automation for less, and for installation inside a well the submersible SBA is best.
How much does a water booster cost?+
In our range, prices start at about €235 (Grundfos JP hydrophores) and go up to about €720 (submersible SBA). The most popular SCALA1 costs €450–570 and SCALA2 ≈ €660. The price includes the automation — no separate pressure vessel is needed.
What is the difference between a floor-standing and a submersible booster?+
A floor-standing booster (SCALA1, SCALA2, JP) is installed in a dry room — a utility room or a sauna chamber — and draws water from wells up to 8 m deep. Submersible pumps (SB, SBA) are lowered into the well: completely silent, they take no indoor space and suit deeper wells.
What is the difference between a water booster and a hydrophore?+
The terms overlap. A hydrophore is the classic setup: a pump with a pressure vessel and automation (e.g. Grundfos JP). A water booster is a compact all-in-one unit with pump, automation and protection integrated (e.g. SCALA1, SCALA2). Both keep your home's water pressure automatic.
Can a water booster be used for garden irrigation?+
Yes — SCALA1 and JP are well suited for garden irrigation and rainwater reuse. If irrigation is the main use, also see our irrigation pumps in the shallow-well pump range (SB, SBA, JP).
Which water booster suits an office?+
An office needs a quiet, automatic booster that keeps pressure steady when several taps run at once. For a 5–20 person office we recommend Grundfos SCALA2 — quiet, constant pressure, integrated automation. A smaller office or retail space is fine with SCALA1; larger buildings can use a CMB booster set.
Why won't the water booster start?+
The most common causes: no power or an unplugged cord, the protection has tripped (e.g. dry-running — the well is empty), a faulty pressure switch or a worn capacitor. First check the power and the well's water level. If the pump still does not start, contact us — we help diagnose the fault and find a replacement if needed.
Why does the water booster not stop, or switch on and off constantly?+
Constant cycling usually points to a leak in the system (a dripping tap or toilet cistern) or incorrect air pressure in the pressure vessel. If the pump keeps running with no water draw, the pressure switch may be faulty or the non-return valve may leak. Fix leaks promptly — continuous running wears the pump and wastes electricity.
Why does the water pressure fluctuate in the house?+
If pressure drops when a second tap is opened, the pump is undersized or you have a classic hydrophore that holds pressure within a range, not constant — SCALA2 keeps pressure perfectly constant even with several users. Fluctuation can also be caused by a clogged filter or a low well water level.
