Overcoming No Provision for Concealed Ductwork: Indoor Pool Dehumidification

In the picturesque town of Robertson, NSW, Zenith Ventilation was engaged to install a dehumidification system in a newly built residential home featuring an indoor pool. While the property was modern and beautifully finished, it presented one key challenge — there had been no allowance for concealed ductwork or mechanical ventilation in the original design.

A Space Without Provision for Ductwork

Because the home had not been designed with integrated ventilation in mind, traditional concealed ductwork wasn’t an option. Ceiling voids were unavailable, and there was no space to run ducts through internal walls. However, the need to introduce warm, dry air and remove humid air from the pool room was non-negotiable. Left unmanaged, excess moisture would soon lead to issues such as fogged glass, mould, and long-term damage to internal finishes.

Installing the Dantherm DanX2HP System

Zenith Ventilation was appointed to install a Dantherm DanX2HP Indoor Pool Climate Control System — a highly efficient unit well suited to indoor aquatic environments. Designed to regulate both humidity and temperature, the DanX2HP combines a double crossflow heat exchanger with an integrated heat pump, delivering heat recovery of over 100% while keeping outdoor air intake to a minimum.

Overcoming Limitations with Smart Installation

With limited space to work with, Zenith Ventilation installed exposed steel ductwork mounted directly to the ceiling. This practical choice turned out to be an aesthetic win as well — delivering a modern, industrial look that blended seamlessly with the home’s architectural style. Eyeball-style vents were positioned along the ductwork, allowing targeted airflow to be directed specifically toward the windows and glazed doors, controlling condensation exactly where it was most likely to occur.

High Performance in a Demanding Environment

Once installed, the system performed as expected. The air in the pool room became noticeably more stable and pleasant, with consistent temperature and humidity levels. Fogged windows were no longer an issue, and the risk of corrosion and dampness affecting the property was significantly reduced.

A Showcase of Adaptability

This Robertson installation is a great example of how Zenith Ventilation delivers quality results — even in less-than-ideal conditions. While concealed ventilation systems are often preferred for new builds, they aren’t always feasible. This project demonstrates that a high-standard mechanical ventilation solution is still entirely achievable with the right planning and execution.

Project Highlights

• Systems Installed — Dantherm DanX2HP indoor pool climate control system with neatly exposed steel ductwork and targeted eyeball vents.
• The Challenge — An indoor-pool home built with no provision for concealed ductwork — no ceiling voids or wall runs available.
• The Outcome — Stable pool-room humidity and temperature, no more fogged glass, plus a modern industrial ductwork aesthetic.
