What to Look for When Choosing a Water Softener in Ireland
1. Water Hardness Level
Use a hard water test kit or consult your local water supplier to understand your hardness level in ppm (parts per million). Areas like Dublin, Cork, and Galway typically experience high levels of limescale, demanding robust softening solutions.
2. Household Size
Choose a unit that matches your daily water usage. A larger household will benefit from higher capacity metered systems, while singles or couples may opt for compact block salt units.
3. Installation Space
Measure your under-sink or utility room area to ensure the softener will fit. Some systems, like the Harvey TwinTec, are designed for tight spaces.
4. Salt Type
-
Tablet salt: Common and cost-effective
-
Block salt: Easier to handle but more expensive
-
Granular salt: Suitable for specific systems
5. Support & Warranty
Buy from brands that offer installation, service plans, and extended warranties to ensure peace of mind and long-term support.
