Low-temperature heating means running the system with supply water around 35–45 °C instead of the 60–75 °C used in traditional installations. It is the key to efficient heat pumps and condensing boilers, but it changes what the heat emitter has to do: at low water temperature, an emitter must expose far more surface or move […]

A modern building rarely needs only heating. When a reversible heat pump or a chiller supplies chilled water, fan coils turn that water into comfortable cooling — from the same hydronic circuit that provides heating in winter. This makes fan coils the most flexible emitter for year-round comfort, and a natural partner for heat pumps […]

Heat pumps are the fastest-growing heat source in professional HVAC, but they only reach their efficiency potential when paired with the right emitters. Because a heat pump delivers water at a much lower flow temperature than a gas boiler, the heat emitter has to release enough heat from cooler water. Hydronic trench heaters and fan […]

A fan coil and an air conditioner both cool (and often heat) the air, so they are easily confused. But they are differently engineered systems. Let’s look at how a fan coil differs from an air conditioner and which to choose for a home or a project. For the basics, see What is a fan […]

A freestanding convector is a heating device that stands on the floor and runs on a water-based heating system (boiler or heat pump). It is used where recessing a unit into the floor is impossible or impractical, but a tidy heat source is needed beside the glazing. Important: this is a water device, not a […]

Fan coil units differ by mounting type, number of pipes and casing design. The right type ensures efficient heating and cooling and blends neatly into the interior. Let’s go through the main types of fan coil units. For the basics, see What is a fan coil unit. Fan coil types by mounting This is the […]

A chiller and fan coil system is a centralised solution for cooling and heating buildings, where the chiller produces chilled (or, when needed, hot) water and fan coils distribute it across the rooms. It is the standard choice for hotels, offices and retail buildings — anywhere many rooms must be served from a single central […]

Fan coil units are connected to the system using one of two layouts — 2-pipe or 4-pipe. This determines whether the system can heat and cool at the same time, and how much it costs. Here’s the difference and how to choose. For the basics, see What is a fan coil unit. 2-pipe fan coil […]

The right fan coil unit delivers comfortable temperatures, runs quietly and saves energy. The wrong choice leads to insufficient capacity or excess noise. This guide covers what to consider when choosing a fan coil unit. New to the topic? Start with What is a fan coil unit. 1. Capacity (heating and cooling) The key parameter. […]

Ducted and cassette fan coil units are two of the most common types for commercial and residential projects. Both heat and cool using water, but they conceal and distribute air differently. This article compares ducted vs cassette fan coil units. For the basics, see What is a fan coil unit. Ducted fan coil units (DF) […]
