ADEN GROVE, NEWINGTON GREEN N16

A Complete Low-Carbon Plumbing & Heating Transformation for a 4-Storey Townhouse

A Modern Home Needs a Modern System

Older London townhouses were never designed for today’s expectations of comfort, efficiency, and sustainability. At Aden Grove in Newington Green, the existing gas boiler and ageing plumbing simply couldn’t deliver reliable heating or consistent hot water across four floors.

The brief was clear:
remove the outdated system and replace it with a modern, energy-efficient setup that works effortlessly — everywhere in the home.

This project required careful design, precision installation, and a future-ready mindset.

PROJECT SNAPSHOT

✦ Location: Aden Grove, Newington Green, London N16
✦ Property Type: Four-storey terraced townhouse
✦ Scope: Full plumbing and heating system replacement, air source heat pump, unvented hot water, underfloor heating, radiators, two bathrooms, commissioning and handover

THE PROBLEM

In multi-storey townhouses, outdated systems create daily frustrations:

• Inconsistent temperatures between floors

• Slow or unreliable hot water

• High energy usage with poor performance

• Limited control over heating zones

• Systems built for gas — not the future

This property needed more than a like-for-like replacement.
It needed a complete rethink — designed for efficiency, comfort, and long-term sustainability.

THE SOLUTION

We delivered a fully integrated, gas-free plumbing and heating system, designed to perform reliably across all four floors.

✔ Air Source Heat Pump System

Replacing the old gas boiler, the new heat pump delivers efficient, low-carbon heating designed for modern living.

✔ Unvented Hot Water Cylinder

Provides strong, consistent hot water pressure to every bathroom and outlet — even at peak demand.

✔ Wet Underfloor Heating (Lower Levels)

Installed across the lower floors for comfortable, even heat distribution with smart zoning controls.

✔ Radiators on Upper Floors

Modern radiators installed where faster heat response was required, perfectly balanced within the overall system.

✔ Two Fully Plumbed Bathrooms

Complete concealed pipework installations with premium fixtures and long-term reliability.

✔ Smart Controls & Zoning

Weather-compensated controls and thermostats to maximise comfort and reduce running costs.

OUR PROCESS

✦ 1. Design & Planning

Working closely with the client and builder, we designed the entire plumbing and heating layout from first principles.

This included:
– Full heat-loss calculations
– Correct heat pump sizing
– UFH and radiator zoning
– Hot-water demand planning
– Future maintenance access

This stage is where performance is won or lost — and we take it seriously.

✦ 2. Installation

The system was installed with a focus on precision and finish:

• Concealed hot and cold water runs throughout the property

• UFH pipework and manifolds installed before screeding

• Radiators and sanitaryware fitted with accuracy

• Heat pump and cylinder integrated into one efficient system

Every element was designed to work together — not in isolation.

✦ 3. Testing & Handover

Once installed, the system was:

✔ Pressure-tested
✔ Flushed and balanced
✔ Commissioned to manufacturer standards

The homeowner received a full walkthrough covering controls, thermostats, and system operation — ensuring confidence from day one.

CHALLENGES & SOLUTIONS

Tight Utility Space

We optimised the plant layout to house the heat pump, cylinder, and manifolds while maintaining clear access for servicing.

Retrofit Constraints

Careful first-fix planning allowed all pipework to remain concealed, preserving clean finishes throughout the home.

Efficiency Goals

Smart thermostats and weather-compensated controls ensured the system delivers comfort while minimising energy use.

THE OUTCOME

The completed system delivers exactly what the homeowner needed:

✔ Consistent, high-pressure hot and cold water
✔ Comfortable, even heating across all four levels
✔ Lower energy consumption and running costs
✔ A gas-free, low-carbon solution
✔ A clean, future-ready installation built for longevity

This is what happens when a system is designed properly from the start.

WHY THIS MATTERS FOR TOWNHOUSES LIKE THIS

Four-storey properties demand more from plumbing and heating systems. Without proper design, performance suffers — and costs rise.

This project shows how careful planning, modern technology, and precise installation can completely transform how a home feels day to day.
